TDK 8X burner $$140.00 after rebate

Staples is selling the TDK 8X drive for $159 But if you print out this coupon http://prefctr.ddc.dartmail.net/Staples/default.asp?a=376�&e=318164�&g=upuqp�&t=v�&c=8370340171052983 it’s $140 plus change in PA. I believe this is the Plextor 8X drive. I don’t know how TDK is with firmware updates, but I’m willing to hear any criticism on this deal.
