I've not bought any of the UD1S records but from what you say, they aren't worth a hundred bucks each.Sorry, that's not the impression I meant to leave. All of these UD1S releases are wonderful. They sound great and have a HUGE collectability factor. All are out of print, (except for this newest one, but I hear there are very few left).
So, I guess it's up to the potential buyer to determine if $100 (actually now $125), is worth it or not. It has been for me.
