Hi Dennis,
I have the 4x5 model. I'm told that the only difference between the two is the size so I will give you my experience with the DLC. I have used it for about 8-9 months now, and think that it is a great camera. It is light, has lots of extension, and plenty of movements. Sometimes I wish it had geard movements but then I remember how light it is and that feeling goes away. I bought it used so I have never delt with the company but am told that they have top notch customer service.
