Everything arrived well packaged and in good order... It was shipped promptly, but hey, no accounting for the snow storm in the NW... I think UPS calls it an "act of God"... Thanks
Ordered Monday, delivered Thursday - just as promised. Best price among all reputable on-line parts dealers. Saved at least a third off the most popular dealers.
Great selection and fast shipping.  Not to meantion the lowest prices anywhere on the net.
Right product, great price, easy check-out. Waiting for my parts - will update this review upon receipt. Update: the right parts arrived on time in good condition. I will be telling my friends about you guys. Thanks.
