My story with Disney video is similar. When I first got a VCR (1980) my goal was to record all the Disney stuff I could find at the slowest speed for VHS (so the tapes would run 6 hours.) I felt it was a modest hobby. Then Disney got on-board with releasing movies on VHS so I thought I should upgrade. Then along came laser-discs (they were shiny discs like dvds but the size of a 12inch record album.) Finally there was DVD so I bought whatever was available again. When blu-ray was introduced it was a bit slow to catch on (remember the format war between HD-DVD and blu-ray?) I noticed that Disney did a quick upgrade to their DVD catalogue, but this time I waited because I was confident that blu-ray Disney movies were coming. I've bought all the Disney blu-rays and have a library of the titles I'm interested in, which is most of them. I now notice that title like Pinocchio and Bambi are being reissued on bluray for the folks who missed the first iteration of them. Anybody doubt that a 4K release of the whole library is ready to roll out when consumer interest kicks-in? And yeah, I'll probably buy them again.
In answer to the original question I'd go along with the others who say get a decent quality player for the main tv and a cheaper unit for the other tv.
