Heard nothing but bad things about them.
Honda-tech.com , go there and do a search on motor swap vendors. It's a bigger user base so you'll get a better result.

As for my own swap, I went with hmotorsonline. The motor was cherry with good compression across all cylinders. Only issue was I recieved the wrong axles and then later was given a broken axle. I also had some issues getting all the parts that were promised with the swap. Other than that it went pretty well.
