I was looking at NWA's website, trying to determine if I wanted to spring for the new HD5 gantry. From the reviews I've read, it sounds like it's a worthwhile upgrade. However, NWA's website says that they are sold out. Does anyone know when they will be in stock again?

I'm also assuming that the HD5 will work for my machine, which is a Shark HD with a working table size of 25" x 52". I'm told that it's not classified as an HD4.
