If collecting LD's is a fetish, does that make one a pervert? ;)
I got my Pioneer 704 repaired and refurbished earlier this year by these guys...

I had almost written off my player as scrap before I found them. I actually think it runs better now than when it was new! (The THX-1138 LD capture I sent to myscamore has benefited from it too.) They also sell refurbished machines. Well worth checking out.
