collectible tv's

[bre's dad]

I've new to the tv realm. I was basically given a 1949 Arvin roundie (not working, but has potential.) OK, I paid a friend $5 for it & he paid less than that at an auction. How collectible are say some of the older console color tv's, say 50-60's? I've often thought it'd be kinda neat to have a working one sitting around, kinda like what I grew up with. I've seen some really nice consoles on ebay for cheap, but too far away.

Not that I want to turn my house into a tv museum. My basement already looks like a used stereo shop and my wife has forbid me to put anything else in the house, but there IS still the garage...

I know it all boils down to personal preference and what you can find, but are there certain models or lines to look for that might hold their value or be worth more?
