CDROM Brand/Model Recommendations?

Hello.  I just started working at a ripping facility that does tons of 
cd ripping.  We have 12 frankenstein ripping machines at the moment.  
These machines are mostly just older machines that people have had 
laying around.  Of course, several of them experience cd ripping errors 
and now we are considering standardizing on new cdroms (but 
unfortunately not replacing the machines in which the cdroms are 
going).  Is there a recommended brand of cdrom that cdparanoia likes and 
is a no brainer install on Linux.  We need something tht will be able to 
handle hundreds and hundreds of hours of use too.  Any suggestions 
appreciated.

Thanks,
Parker
