I had good luck with them. I've used a few of their SSI brand cams with good results. They do have a really cool catalog but I think you have to pay about 7 bux for it. They carry some neat stuff, like a good selection of Offy intakes with off the wall carb configurations. Lately I've gravitated to either Summit, Jegs, or Northern Auto Parts for most of my stuff, but would still use PAW if they had what I needed at the right price.
