I bought a Scubapro mk25/s600 regulator from them a few years back. At the time, Scubapro had them listed as an authorized retailer. It was one of those "last year's model" deals for quite a big discount vs MSRP so it was a good price, too. No complaints.
I had no problem getting my LDS to service it under warranty or anything like that.
So there, at least one good review
I think that was 4 years ago, however.
