Yes, if you need parts today, parts shop is not the place to buy them. But, with a little planning you can order the parts from them, get a fair price, and order from someone you know you can trust.
I'll admit that I have not bought all my parts from parts shop. I am now trying to plan ahead and order everything that I don't need immediately from parts shop.
These guys have put together what I consider to be the best web site in the world, at least for my needs and interests. My goal is to pitch in what little I can to reward them for their outstanding efforts.
