According to Plextor Japans On-Line-shop the 712SA is now sold out: https://www.plextor-direct.net/cgi-bin/WebObjects/plextor
I’m selling mine so I have more stock than Plextor
The 712SA seems to still be fairly plentiful at the Local Fry’s and Microcenters around here, but probably once the stock they have is gone there will be no replacements.
True. I’ve seen the 712SA in different stores around here but i’ve yet to see a 716SA outside a mail-order-list or on-line store.
