I recently (within the last 6 months ish) got into squonking, no going back!!
Had few bad ones (vaporflask clone and Streamcrave squonker) but on the whole everything else has been pretty good.
M-Vapes make reasonably affordable mech boxes which are pretty good, I got a dual 18650 wooden mech from M-Vapes - really happy with it, solid and simple.
The only other mech I have is a sort of custom classic/tmod customs clone from China, cost $50 with shipping ($18), its a great bit of kit and got me wanting an authentic brass Custom Classic now.
I nearly bough one of the Svapiamo 26650 ABS mods but decided to go for a regulated box from the same place with a evic mini 75w tc board in - my current work mod
