I recently purchased a Power commander 3 USB from speedwerks.com. I paid them on 10-29-2004 and just called them to find out what is going on with my order since the only correspondence I received was an automated invoice. The lady told me they "just finished boxing it up." 5 days to box up a brand new pc3 and ship it????? Gimme a break. Only reason I bought from them was they had the best price. But you sur as hell sacrifice the service. I really wanted it here for my tracday on Sunday. Probably wont happen though. If your willing to sacrifice service for $$$ then go with them. If not, buy somewhere else.
