You can give one of the Nemesis clones a whirl. They seem to be popular. Make sure to read the discussion page before buying, to read up on any known issues with that particular item. Also, don't go cheap on the batteries, the charger, and some good meters. Ohm meter and volt meter, or a good multimeter are needed for mech mods.
For rebuilding supplies, check out Lightening Vapes or Temco for Kanthal. Lightening Vapes has other rebuilding supplies too, like wicking, tools, etc... I personally prefer the Japanese cotton pads for wicking. I think it's easier to estimate the right amount needed for my coils as all the fibers go in one direction. Could be in my head, but I think theres better taste as well. I get bags from Muji.com. $2.50 per bag that'll last a lifetime, plus around $5 for international shipping. Comes fast though. Others prefer KoGenDo, another brand of the Japanese cotton, but it's pricier and usually out of stock. I think Muji is the same thing in the end. Cotton from CVS works as well, and I was happy using that, but then went and ruined it trying the Japanese stuff. Ordinary cotton from a pharmacy is cheaper of course.
