There is a guy named Doug Laird who goes by the name of px20162124 as an Ebay Seller. His Ebay Store is R and D Discount Bowling. I recently bought a Track Xception 5.0 from him. He is a super nice guy to deal with. He went above and beyond to please me, the customer.
One example in my transaction, he (his girlfriend) accidently sent my ball USPS parcel post when I specifically requested Priority. He sent me another ball (and let me pick different specs than the auction I won cause after getting with tenpinspro and EX I decided to go with a little shorter pinout)and trusts me to return one of them. (this was very important because I have an  overseas military FPO address and it takes two months+ to get standard mail packages vice 10 days for Priority shipped.)I don't know many sellers that would've put two balls in the mail when they've only been paid for one!
I just received the Priority one (shipped second). Looks great. Check out his stuff. Some first quality and some seconds. Prices are pretty good, too.
