<< folks, be aware that both overstock.com and justdeals.com now hosting at yahoo, they are unfair, bad merchant selling junk component at a price that seem a little cheaper then retailer but that's how they get you, so becareful plz. >>
Granted that you should always be careful... Always use a credit card so you have some leverage!
But I just wanted to say that I've bought from both of these companies before without incident. From overstock, I bould a Palm VII for $99 AR at a time when it was selling for $299. More recently, I just got my 2 wireless bridges from justdeals.com for $300 for both. These are listed at $1100 EACH, and selling at CDW, and many others for $800 or so EACH! The showed up brand new in box just as advertised minus a cable. Called Proxim the manufacturer, and they overnighted 2 cables free of charge while apologizing and admitting that some of them had gotten out without the cable.
But yes be careful, be sure of what your ordering, and who your ordering from... For me it was worth the risk. I got a enterprise quality wireless bridge setup (complete with bridges, cables, antennas, lightning protectors, etc) for $600, about 1/3 of the lowest price I was quoted from others.
