I saw a Plextor Premium on net today for 250 bucks, seems a tad high, but if you really need one, worth it. After all it is a critical gear item.
I did find a NOS 716 recently for a reasonable price, but those finds are getting rare as hens teeth.
on a related topic my supplies of TY discs keep creeping down in quality, still within spec, but not super low errors like 5years ago.
I suppose sending a DDP image on a DVD-R will supplant CD-R masters at some point.
