Thanks for the reply, Steven. I called again and left a detailed message.
The site shows their merchandise, and they carry an extensive inventory, but since no one I know has used them, I want to get some feedback before I place an order.
Since I live in the eastern US, I use Comet for 90% of my needs, and they are phenomenal. Over the years I have also ordered a bit from Acceleration, Fastech, J3, and Franklin, the first two of which have great webstores. Every time I need to call either of these, someone answers and helps me out–it puts me at ease knowing someone is manning the phones.
