Query: DON'T BUY THESE UNLESS YOU NEED COASTERS! THEY ARE GARBAGE!!

I bought 200 of these (2 - 100 disk Spindles) in June of 2004. They were GREAT! I had 4 bad burns and the rest were flawless.In October I ordered 400 more (4 - 100 disk Spindles. Apparently, Memorex went to a different manufacturer for the new disks. THESE NEW DISKS ARE AWFUL. I HAVE THROWN AWAY ALMOST ALL OF THEM. I ESTIMATE MY SUCCESS RATE IS LESS THAN 5 OUT OF 100!!!I am outraged by this and feel ripped off. I will never buy them again. I can't take a chance ordering Disks from Amazon because I cant return them once I open the Spindle. THREE HUNDRED DOLLARS WASTED!
