I can't think of a place that offers better customer service. I ordered 2 engines Thursday night, they didn't charge me for shipping. The engines arrived today - not sure how they pulled that off, mail doesn't usually travel quite that fast. When I opened the box, not only engines but glow plugs and 4-40 bolts to mount them with. I don't give praise lightly, but I highly recommend them. I've never had anything but good experience dealing with them.
