The rules are a huge ham-fisted PITA. I was extremely leery of that site after reading Magnetic's and other stories like his. However I eventually joined when I couldn't find the parts I needed for my A500 build anywhere else, went through their mind-boggingly complex registration process where it seemed like I had to agree to a new set of terms every time I visited the site... but was rewarded by meeting a fantastic seller who actually had everything I was looking for and was willing to cut a deal that we both were happy with.

Give it a shot, IMHO, and good luck!
