I have been using PNY Black Diamond CD-Rs for quite a while.  I
have only burned maybe 2-3 coasters, and those were my fault. I
use an HP 9300 ATAPI at 10X.
 
I assume you are talking about the cheap PNY's on the 50 ct spindle.
We distribute PNY, and the Black Diamonds are about 20% higher cost, 
but work much better.  

If you are interested in getting the Black Diamonds,  I think I could 
work out some kind of a deal for the LUG.  It would be about $22 per 50
count spindle.  We usually only carry 5-10 at a time, so you would have to 
allow order time.  

Let me know if you are interested.  It would have to be through the LUG, not 
individual orders, since we are a wholesaler.
