Anyone had any experience ordering a part from these guys? I've been getting the runaround from them ever since I ordered a piston for my 650-B way back in late April. I don't like to be pessimistic, but it's looking like the best thing to do is give up on the part ever showing up and buying another one from somewhere else. Somehow they have no record of my order, and I'm now jumping through hoops and digging through records and old emails to resolve an issue that is clearly originates on their end. It's becoming a real pain.
