Bought things from LMC and so far so good. They have been very cooperative in returns, even when I goofed.

Their prices on some items are high as compared to same things sold at Summit or Jegs. Chevy Duty has been good too, but they have a lot of backorders whenever I order from them lately. They even made good on a mistake they made on their catalog and with the return shipping back and forth, I don't think they made any money out of me on that deal.
