Personally I really like the notcigs M1A1, but lavatube should be fine with any normal tank.
If you want a real work of art, in won't-crack-with-iffy-eliquids, try a phiniac pyrex tank.
If you use eliquids that are on the might-crack-
tanks list (maintained by my4jewels), but don't want to spend the $ on a phiniac, try the smoketech DCT polypropylene
tanks. They are pretty low cost, and easy to cut down for standard length cartos. Just stuff a piece of wooden dowel in, and use a normal pipe cutter.
