Has anyone bought from these guys?

I really miss my 240, but it needs a new engine and I don't trust junkyard engines and can't afford the ~$2600 for a remanufactured long block. Then I found this site: http://www.tbolt.net/Nissan_CID.htm.They're selling KA24DEs for $1450, but that so much lower than everyone else, so whats wrong with it?

BTW, I probably don't need a whole new engine, but I don't trust this one. Before I had it, it was my mom's and she ran it for so long with the same oil it turned to sludge and trashed everything to do with the timing chain. She had that stuff replaced, but now its making tapping + dry bearing noises. I'd rather a new engine than fix this one and have something else break later on.
