Vamo is a good first time purchase, and I've used my Vamo V5 quite a bit. They're a good low priced starter kit. Once you get your ego, you'll notice a big difference over the Blu's. Rebuilding on an Ego battery is not really recommended. I'll post some quick tip information on batteries to explain a bit.
Ecigarettes are, of course, battery oriented. Most of the vapor comes from what the battery can supply matched with what coil you build. The more power you supply to the heating element in your Ecigarette (AKA coil), the faster it will boil (vaporize) the E-liquid, which produces steam (vapor). If you look at your Blu ecig, you have a battery and a cartrige. the cartrige has a tiny coil.. of course, that's to match the tiny battery. Of course, you know tha even that tiny coil drains that battery fairly quickly, so the next best step is to simply go with a bigger battery.
The next logical size up is the Ego. This is where I consider a true starter kit. The larger format can store approximately 5 times the ammount of a "cigalike" like a Blu. It's just simply larger. Both the blu and Ego's use Lithium batteries, which can output about 4.2 volts. Usually, they regulate it down to 3.7 volts to extend battery life as well as protect the battery from being drained too fast. Not only is there the voltage, there is something called Amps. Think of Voltage as speed, and amps as quantity. Both the Ego and the Blu ecigs supply power at the same voltage, but the ego's can supply a bit more power overall. So, they can support larger coils even if they are using the same voltage. larger coils means more vapor, and a better experience overall.
The reason rebuildables aren't very popular with the Ego's, is even though Ego's can support a higher amperage limit, they still don't provide enough for a true rebuildable. I have a variable voltage ego, and I do have a rebuildable for it. But, I have to keep in mind that I am very limited in the builds, and I'm stuck using 32 or 34 gauge wires.. which is a pretty thin wire. If you try to use anything larger, the ego's just don't supply enough aperage to power those coils. That's not to say it isn't possible, but it's really not very feasable. I would stick with clearomizers, and stick with 1.6 ohm resistant coils and above.
Now, the next step above the Ego's, is the Variable voltage/wattage mods like the Provari, Vamo, and Itaste (to name a few). Those use even larger sized batteries, and are regulated. Those are regulated, and they themselves have their limits. The vamo, as an example, have a 5 amp limit. Ego's usually have a 2-3 amp limit, and I don't know what blu's are, but I bet it's quite small. 5 amps is a good starting limit for a single coil rebuildable. It also widens the options for the type of wire you can use as well. Things like the Kayfun can be used on these devices easily. However, you have to stay at 1.2 ohms or above with these. They are good starter units, and may be your all day vape. There's no need to go any higher, and they take a wide range of batteries. Recently though, they've come out with more powerfull variable voltage devices. The DNA 30 devices comes to mind, and the DNA 30 can supply 10 amps of power. These start to need specialized batteries capable of a higher discharge rate. Some devices come with built in batteries, but others require special batteries capable of the high drain. This is also where variable voltage can support more than one coil and work well.
Well, if you were to get rid of all electronics, and connect the coil straight to the battery, you'll have what's called a mechanical mod. With these, the coil determins how many amps are being drawn directly from the battery. This is when rebuilding is definately wanted, since the build determines how much power is being used. The mods are usually simple, and usually have locking mechanisms to prevent it from firing when it's put on a table or in your pocket. Without limitations, you have the full capability of the battery you are using, and some batteries have up to a 30 amp limit. This is also where it can become dangerous if you don't know what you're using, since trying to draw too much power can over-work the battery causing it to vent hot gasses.
your Plumeveil I would only recommend with either a DNA 30 or a mechanical mod. If you want to go on the safe side, I would suggest getting a DNA 30. If you get a DNA 30 that uses a battery, I would suggest getting the Sony VTC4 or VTC5's, since they are one of the safest and best batteries on the market. I do not suggest getting a mechanical mod until you are familliar with rebuilding coils. I can go into detail about coil building, but I believe I've been long winded enough already.
Anyways, good luck, and welcome to the forums. Be sure to ask many questions... the worst question is the one never asked.
