I collect the little portables such as the Sony "Watchman" series with the lollipop CRT and other smaller pocket sets of the era. I concentrate mostly on CRT sets, but have a few LC display b/w and color sets.
These things hit the thrift stores (and eBay) in large numbers after the shut-off of full power analog broadcasting.
They don't take up much space, a decent collection can be stored in a shoe-box. :D
I posted some pix here:

It has been many years since I have seen a color "roundie" in a thrift store! :no:
Other collectors, eBay and occasional Craigs list are the most consistent sources these days.
