First off tannerrex, welcome! Second, that's a loaded questions because there are many variables that only you can answer that are not given in your question. Having said that lets deal with some hypothetical's...
Looking for low power regulated device (VV/VW)
Your options include things like the Vamo, Innokin MVP, SID, VTR just to name a few.
Mechanical Mods/Drippers (RDA)/Genesis Attys (RBA)
If you like to tinker and feel comfortable with a screwdriver then a mod may be right up your alley. With your choice of atomizer you'll be ready to step up your game so to speak to a whole new experience. With the choices of atty's currently available it can be very daunting and while there are many here who are biased one way or the other, IMHO I think that if you chose this route say for a (RDA) dripper then a simple 3 post model will get you started (Patriot, Omega, IGO-M). If you choose to go with a Genesis style atomizer or tank RBA then (kayfun or kraken) may be a good starting point.
High Power Box Mods (Regulated/unRegulated):
Here you have mod both regulated and unregulated that can handle the spectrum of the vaping world in terms of power. From 3.0 - 1.0 ohm coils to .9 - .3 ohm coils safely. We are starting to see box mods that are handling even lower ohm coils in the .2-.1 range. Here your have mods such as DNA20/30/50 watt based mods as well as the SSG330/350 chip based mods that will allow for higher wattage upgrades by downloading new firmware if you are in to that.
Within each of these groups there are both originals and clones (copies). There are also a host of upgrades, customizations and retrofits to personalize,improve and enhance you mod to your liking and it's all dependent on your vape budget.
You choose!
