This thread may be dead granted but in case someone else decides to go with an air compressor, the link below seems to have some pretty fair prices and some quality stuff. I picked up my strap and shackles from these guys and they knocked some off the price just for the hell of it. And as I mentioned before, they don't carry crappy products. I still prefer my powertank, but than again I'm no player hater.
