Both of your suggestions had occurred to me..black friday (I'm also shopping for a backup usenet subscription) and staples coupon (yes I do get them)
I had also read on smallnet builders, when the 66U was introducted that the ram was 1/2 utilized..I see now merlins firmware corrected that.
When I was shopping in tiger for the cisco router that I just got for work - the saleman told me it has the 'superior' internal antennas - I think now he was feeding me a load of bull. That'll teach me for impulse buying.
Most importantly..the 66U is a nice looking router
