Several good point brought up here. I am lucky to have an understanding wife. (and the understanding is, I have 2 rooms in the house to do with what I want...and that is IT.) I am starting to practice what Phil suggested. I also spent many years dragging home any and all sets, basically anything that fit my wallet. I basically looked around one day and realized I was operating an orphanage for old TV sets. I wish it was easier to share the surplus.
I have become adept through the years at sneaking stuff into the house. The first one was when I was 14 years old and managed to have a 21" RCA bw console delivered by a local antique shop. They brought it in the half hour between me getting off the bus and my Dad getting home from work. Just enough time for me to drag it back to my room. It was weeks before Mom & Dad found out! Nowadays, unless my wife is with me when I pick up a set, I don't bring it up. Why worry her?
