To Buy a New or Move an Old

TV that is. I have a perfectly good TV at home. A 28" I do believe, that i got a few years ago when I worked at Walmart, and it works great, it's nothing fancy though, it doesn't have picture in picture, or HD, but it works, and that's good enough for me. Except it's bulky and heavy, and there is no way I can lift it alone, so moving it out here in my car is out of the question. So I either have to wait till I have enough room and can convince my dad to come down with a load of crap in the Van, or I could buy a new TV, preferebbly something lighter (ie: Skinnier). There are a few decent sized one's that I could get for under or around $600, but do I want to fork out the cash for a shiny new LCD flat screen TV?
