I wish Photobucket would let me navigate to the picture of my wall of color sets from the years when I was stuck in a small apartment room.
I've learned to stack and or shelve stuff. I literally have walls of sets that I can turn on and watch...I've been known to watch the same show on 3 sets at once, or 3+ different shows at once. It's sort of like the old intros to robot chicken.
Once I buy my own home and am not limited to the basement, my bedroom and display room I'll probably be set up like Walter Matheaus character in Grumpy Old Men where I can walk half way across the house and not have my eyes off the program on some TV.
I do actually sell off stuff. I reevaluate my collection and sell off the bottom 10% of things on the likeability scale and or things that don't fit themes or categories I want to collect. The ETF is my primary selling ground, though the radio clubs within 3 hours drive of me sometimes result in TV sales...I collect radios too and bringing TVs to radio meets sometimes gets leads on TVs and other stuff.
I'm at the point where with ~100 sets I'm happy with what I have and have almost stopped buying new stuff/gotten pickey.
