As much as I like GP, I've never seen a company go so far out of its way to avoid warranty service. I recently contacted them to get a list of both online and local authorized distributors. One would think that living in West PA, there might be a fair few. Wrong.
Tool Source is literally the only authorized online distributor, and the nearest "local" distributor is 70 miles away in the middle of nowhere. That seems to be the pattern for their so called "local" authorized distributors, none are near any cities or even large towns, all seem to be out in bumf@ck, Yourstatehere.... Also, warranties are only honored through authorized distributors, they will not deal with you directly.
As I see it, your better off going w/ Sunex, but if you must get GP, Save yourself some money and just buy through amazon or whoever has it cheapest, if something breaks there are tons of e-tailers you can buy the individual part from since GP's turnaround time is about as fast as paving a driveway with a fork and high hopes.
