I hate to hear that Chad is not keeping up with folks. He was my go to guy for a long time years ago, well before the SF4 craze and it's too bad he couldn't recover after it. He was always a gentleman and his service was top notch, I haven't bought anything form him in years, simply 'cause I had way too much overhead in parts and I still have left overs. Haven't bought any arcade parts ever since, except for a few members at ZDTF.
I keep hearing great things about Focus Attack though, they have a very nice website and apparently are partners with ART Hobbies (The plexy guys) and some stick builders. I think that's very cool, keeping the circle tight with top quality partners to provide all kinds of services related to arcade hardware.
