How about a forum to post purchase experiences (good or bad) with vendors, dealerships, etc? There have been times where something like that would have saved me some headaches.

Sometimes a place has a slick website and no product, or crappy customer service (Newport Cycle Parts), or a crummy website and good service (Parts411), it can be difficult to tell.

This would be an easy way to help each other out, without having repetitive threads asking "What about these guys? should I order from them?"

Just a thought.
