My opion on buying parts. To anyone buying parts...... you the buyer has to take a certain amount of responsibility yourself and completely check out the item regardless of the seller - no matter who it is. The items we buy are usually used and sold "as is".
I myself have been taken simply because I didn't check out the item closely before leaving with it; my fault completely. If I would have looked closer I wouldn't have bought the item. You do have a choice to buy or not. If you don't know what to look for take a friend who knows more.
