Hey Doug I don't think its a strange hobby-- just a little 'unconventional'.
I try and rotate through a few different tv's too.... even tried using my portacolor in the kitchen but that didnt last long since direct afternoon sunlight washes it out too much.
Right now I'm using my ctc97 as my daily watcher (which I know is sacrilege considering I'm zenith2134) and its all the TV I need at this point. However we both know that it'll get traded out when a bigger or better vintage set passes through. Thats the fun of it for me.
