ehh....alright, well I'm gonna say this once and the let you be scammed.
PricingDepot.com appears to be a website that finds you the best deal, and then your purchase runs through another company. I searched for the FX1 and the VX2100 and both times PricingDepot.com came back with a too-good-to-be-true price from SonicCameras.com. Hm. ResellerRatings.com says SonicCameras.com is a scam. Their rating is .87 out of 10. That's BAD! And the comments are just as bad. Here's the link http://www.resellerratings.com/store/Sonic_Cameras
I'm happy that your buddies bought some stuff through PricingDepot.com, but I'm guessing that they weren't cameras purchased through SonicCameras.com
