I've been using the Ego Booster from happyvaper.com for about a month now, and I gotta say it's probably the best ecig investment I've made to date. Basically, the eGo batts are useless (imho) unless you're willing to use nothing but LR atties and carts; 3.2V doesn't get you very far with resistances much over 1.8 ohms, give or take. So, like many, I relegated the genuine Joyes to the cigar box and used my SLBs and E-Power 18650 exclusively. But I really wanted something with more juice, and, being too cheap to spring for a ProVari or yet another fixed-voltage mod, I decided to try the Ego Booster - $70 approx. with shipping seemed reasonable and it would work with my dusty Joyes AND the E-Power. Pretty sweet.
Unfortunately, the first unit was defective - barrel came loose from the switch assembly, but was quickly replaced by Jack at happyvaper. Now I have two since the original still works.
I have to say that these things are really, really great. For one, they handle 3 amps where other VV mods (which shall remain nameless but start with "Pro") only tolerate 2.5. On an eGo batt this isn't that big a deal, but if you use, say, an IMR it does seem to make a difference.
Now if all you have is a bunch of pen batts or SLBs, a ProVari or other VV unit might be worth the investment ($200+), but if you want to take full advantage of your Joye and/or replaceable battery mods the Ego Booster is really worth looking into. I think they're making a stainless version now, which would probably be the way I'd go since the black coating tends to flake off. Check it out! Ok, end of rant...
