Hrmm, that's not the page I was looking at, maybe I've gotten confused in all of the wrench research I've been doing.
Either way, let us know if you get anything back from them. I would love to see a SAE and metric seperated version. Also, the big complaints were that it doesn't hold a "standard" set of wrenches, it only goes up to 3/4". Most set's I've ever seen go to at least 7/8", some to 1". I could see buying a number of these if they made them in the right sizes, 1 for standard combo's, stubbies, ratcheting, flex ratcheting. I would be happy with something along the lines of a tray that could handle 1/4" - 1" to start with.
I think Sort A Tool has the right idea, they just need to expand the line and run with it!
