A TV can realistically be setup on a piece of furniture instead of wall mounting. I love my projector, but a TV definitely is easier.
I would recommend, for someone moving a lot, a quality LED LCD display. They are very good looking, but not as heavy as plasma and will provide excellent image quality in a variety of unknown conditions. Realistically, they provide the most 'flexible' image. Not the best, the most flexible.
With that said, if you have the budget for a D6000+ series of Samsung display, at the size you want, then that's what you should be getting. They are light enough for one person to setup and install easily. Keep your packaging so that you can move from location to location far more safely and easily.
Something like this would be near the top of my recommended list:
Amazon.com: Samsung UN55D6300 55-Inch 1080p 120Hz LED HDTV (Black): Electronics
Many people would (and should) argue with you about audio as audio really does matter a great deal to a good experience, but with a lot of moving, I can understand your resistance. Perhaps a good speaker bar with wireless subwoofer at some point will give you a solid performance boost if you would like.
Remember! The best 2D TVs also support 3D, whether you use it or not, is irrelevent to the quality you are purchasing.
