The best bar none is Plextor 12/10/32 w/ BurnProof, you can get it IDE now, and SCSI soon.
If you want price/performance then look at that Yamaha's they make a damn nice drive to, and it's not as expensive as the Plextors.
Personally I don't give a crap about burnproof and my 8x8 Yamaha was 2/3s the price of a 12x10 plextor, but the plextor is the best, epsecially if you plan to do alot of burning (I don't do much, that's why I went for the yamaha)
