I'm just gunna jump in and say AGM is a pretty decent company if you don't mind the pot metal body. I love the worn look on metal guns and my AGM m4 looks great because the finish has worn off some (but then again, I treat my guns like crap, so go figure).
I've been running it stock (besides a m110 spring) on a 9.6v for two years with one problem (edit: the cutoff lever wore down). The internals on my model were decent and the shimming was sub-par, but not horrible. Also, the wiring doesn't completely suck, the connection to the fuse assembly is just weak (and thats where a lot of them break). Bypass that and you're set to go.
Anyway, a lot of people seem to either love or hate AGMs, its possible my rifle was the lucky one, but the few I've worked on (besides mine) haven't had many problems either. (both of them had broken wiring harnesses at the fuse connection, and one of them had a worn down cutoff lever).
And the OP needs to get back to us to tell us what he is looking for exactly.
