sunoco, I'm nowhere near NJ however I just want to let you know about 2 months ago I knew ZERO, NADA, NOTHING about arcade cabinets, Mame, encoders, wiring, etc, etc, etc. I have since then started 2 CABS and learned a hell of alot from the people on this forum and searching the web. If you have the time (or make the time which most of us do), it's worth installing these things on your own. If you're confused or just have no start, search the web and/or the WIKI for answers. You'll be surprised as to what you find. Also IMO, I think most people here just don't do house calls. With that being said, after your initial research for your problem post a detailed question and typically you'll get a good starting response. It may take a few days to figure things out between replies but it's better than waiting for someone to get back to you about a house call. Just my 2 cents, but building it yourself is half the fun. Good luck and welcome.
Cheers!
