Reddit mentions of Smart Strip LCG5 Energy Saving Power Strip with Auto-Switching Technology and Modem/Coaxial Surge Protection

I would recommend Sanwa buttons over anything else except maybe gamerfinger. Those are new and use Cherry MX switches. Industry best stick is the Sanwa JLF but if you want the traditional bat top feel of a street fighter cab go with Happ IL competition joysticks. I would recommend the Zero Delay USB Encoder just search for them on ebay there 10 bucks a pop. Less lag then a ipac and dirt cheap plus they will work with a PS3 so you can do a dual cab. You need a special powerstrip like http://www.amazon.com/Smart-Strip-LCG5-Auto-Switching-Technology/dp/B000L9635G you can probably get one cheaper with some googling. If you go with 2 zero delay usb encoders you have a maximum 19 inputs not including joystick thats enough controller space for 8 buttons plus 3 mode buttons which are start select home on a ps3. But you can map them to Player 1 coin and Escape. You should be able to get by with 20 buttons . Most front ends emulators and software let you map whatever buttons you want you only have to use specific buttons if you dont want to have a specific button tied to something. I would recommend Hypserspin for your cabinet front end.
