Yeah we've got a thread or two going about the HGs (my 3 are HE4s) and they're worth looking into at least. Probably going to carry a small premium for a bit though.
As to the 100w... without having a working handle yet on which mods are series or parallel, or the implications of each, I'm going on the idea that there are a ton of 120w, 150 and 200w reg mods plugging away on HE2 &4s, 25Rs and ??? (what the hell's the third one? I feel like Rick Perry.
)
I won't look at any but those three (+ the new HG) and if they handle those mods, and what are probably a hell of a lot of lower res builds, and big fat power hungry builds... I don't have a concern with anything I'm likely to throw at 'em in a 100w box.
I expect I'll get 25Rs from Jon.
