I don't know the first thing about the internal stuff. Maybe the scope of this question is too vast, but here goes. Shawn, your modded CX40s, how do they differ--in simple terms for a guy who's never taken a controller apart--from the ones that Best sells? I've been curious about Best's for years. Only reason I haven't purchased is all the strange stuff I've read on AA about ordering from that guy.
I've actually got two stock CX40s that are in great working order and are cosmetically perfect so I'm happy with them. But maybe they'll begin to fail one day? As a general rule I'm opposed to modifications to original hardware. But maybe if I knew what I was missing I'd be singing a different song? Again, not trying to hijack your FS thread.
