I've currently got a VT133 I use as my main mod, and a backup Snow Wolf (original) and Dagger. Out of these 3, the closest to "easily dismantled" is probably the Snow Wolf. The VT133 looks reasonably easy to disassemble (from the outside and ignoring the fact that it uses hex bolts) but I'd prefer not to dismember it, the Dagger involves heatgunning (to loosen the glue). Ideally, I'd like a mod I can unscrew X number of screws, and I've got something that looks like a metal box, an IC, and a bunch of buttons. Any recommendations?
