DW and I have just bought a 50" flat panel TV and are trying to figure out a creative way to house the new beast. Our ideal would be to have the thing on a cart that can swing around, so that it could be seen in the living room, or across the dining room from the kitchen.

Does anyone out there have experience with using carts big enough to hold a 50" flat panel TV set? Are they wicked expensive, can they hold a top-heavy display without risk of tipping, and is the mobility worth it? Oh, and where did you get whatever unit you may have gotten?
