I have also had a very good experience with Skalor. And SantaCruzTGP. There are a few other I have dealt with, but I dont remember who they are.
I have only had one bad experience, and that was from Davis? (lives in canada, havent seen him around in awhile) I bought A bunch of TGP parts from him, and there were problems. Radiator, Condensor core to be specific.
EDIT = Would I buy from Davis (Invasion1) again? Yes I would. As mentioned above, I had a bad experience, and I also dont blame Davis for this. It as partly my fault, as well as his. Me for not doing my research befor I bought the items from him. So this is not me badmouthing him, or anything of the sort, its just saying I had a singular bad experience that is not entirely the sellers fault. If this were ebay, I would have given him a nuetral, and not a negative or a positive.
I havent sold anything here, so I cant report as to the people that have bought things from me.
