I haven't called to ask what their prices are though.
I was lucky enough to score a sealed LD-V4400 a few years ago on ebay, and I think it performs better than my now-busted combo player. It only plays Laserdiscs, and is built like a tank! No fancy features like auto-reverse that can break, so hopefully it will last me twenty years. ;)
