I bought this monitor about a month ago, and so far it works fine. I drove up to the guy's store, about 45 minutes away, and he actually has 'tested' models there. He gauranteed they would work, and he includes a power cable with them. Difference is in price, $175 tested, $60 untested. I decided to try and avoid hassle and forked over for the tested. The unit does work pretty flawlessly for me. The units are about 25" wide, 19" high, and 14" deep. There are some frame mounts which stick out a couple inches on each side, widening it slightly. The weight is supposedly 71 lbs. It came with a box, but I had to take it out of the box to fit it in my car. I actually was on a sprained ankle (basketball) and the guy, Jim Rainbow, carried it to the car, unpacked it, and helped me load it in. He was very nice, and took credit card on site. That is just my experience. I'll be happy to answer any other questions. I just started gettign pieces for my cab, and am about to begin construction.
