I've tried a q-510 from Madvapes, $10. Rated at 3 charges, and it comes with a USB charger, atty, and 3 filled carts. The carts sucked (as do most pre-filled stuff from China), but the atty seemed pretty good and the battery lasted WAY more than just 3 charges. Automatic, but they're nice to have around to give to friends or as "emergency rations".
P.S. I think the commonly accepted term is "vaper", but we know what you mean. No Grammar-Nazi's here, lol
