I have bought several items from cellkid22 over the years and would not hesitate to buy from him again. It did take some work and further negotiation on shipping when I bought the full Sparco seat from him, but he was reasonable and not hard to deal with.
Shipping large bulky items is not easy or cheap unless you have experience and know some tricks. Maybe we should have a "How to ship" thread? I have no idea how to cost effectively ship tires, but I know it can be done...
