cosco/sams club monitors

Costco has a Princeton 17 VL1715 25ms, brightness 300 at $359, a Proview at $399 (not a lot of info)
Sams has Nec 17 lcd1712 16ms brightness 260 $396
samsung 173v 250bright, 25ms $398
and two 17 inch sceptre units that I do not have info on


I trust these two merchants as they have great return policies, I was thinking of the princeton.I do note that these stores tend not to be too leading edge. Anyone have any thoughts on these monitors, or is there a killer coming soon that I should wait for. The Hyundai fiasco was a bit of a dissapointment, I am using a 21 inch tube Accuview that is getting dim.
