When I started with a 510, I figured out quickly that you have to "prime" the atty, by taking a short quick draw right after you push the button, then a slow and steady full lung hit, rather than a cheek-draw like you would with a cigarette. You'll probably cough a few times if you do it right, since the water vapor we're inhaling is pretty thick and warm as it enters your lungs. Take things slowly, there is a learning curve to making any PV or e-cig work the right way, even the big custom mods. You may also notice you're not producing much vapor, likely because you've bought a lot of MOSTLY PG (Propylene Glycol) juices. If you find you're not producing any vapor, but still getting a good throat hit, add a few drops of a VG (Vegetable Glycerin) juice of a similar or same flavor, unflavored, mint which mixes well with damn near everything, or menthol which amplifies other flavors. The addition of the VG will produce an enormous amount of vapor for just a few drops per mL of PG juice, and you might feel like you're actually being productive when vaping, rather than being disappointed in your e-cig.
Like others have said, stop spending more until you get the hang of your current equipment. I used a Joye 510 religiously for a year before I got an eGo. The eGo's vapor production put the 510 to shame, but was still not always consistent. I lost the eGo one day, so a few days ago I decided I wasn't going to smoke analogs anymore, and build a box mod for about $8.00 in parts plus batteries, and bought a Silver Bullet tube mod, which is what I'm using now. Once you get into a mod rather than an e-cig type device, bricks will be shat at the amount of vapor you can produce and the flavor profiles you can get out of a juice just by adjusting the voltage a little. My box mod is 4.8v, and the Bullet is 3.7v, and all my juices taste different depending on which one I use.
