They still show up at thrift stores now and then around here. Usually in very small numbers - although two weeks ago about 400 showed up at one - I bought 4 or 5. Nothing terribly rare - although I don't look for things just because they are rare - just things I like and don't have.
I haven't actively gone after lasers for a long time - mostly because I have most of what I want - the ten years or so after lasers phased out were the glory days as people dumped their collections. I think my favorite piece is a Hong Kong laser of "Night of the Comet" - which has since come out on dvd. But it is a pretty neat piece nonetheless.
