I have been diving with Hugys since 2002, doing both wreck and reef photography. I started with an Atlan 81 for Nikon F80, currently I have a FDN-70 for D70 and my new FDN-D300 will arrive any day now. 
The Hugys are fine, rugged housings (and I certainly do not pamper them unnecessarily). Not probably the absolutely best in all regards, but not terrible in any regard either. Ergonomics is the strong area, while some of the (dome) ports leave a bit to be desired. Especially diving with stages you tend to run out of hands doing gas switches and the like and the the ports tend to bump into all sorts of equipment and the acrylic tends to scratch easily.
I deal directly with the factory and I have always been getting good service. Overall, I have been happy, as witnessed by my repeat business with them.
