1Sale offering factory unlocked BlackBerry Q10's for $400
There's been a ton of deals happening on BlackBerry 10 devices lately between carrier offerings, Amazon and various other big box locations. Even BlackBerry themselves have started selling devices directly though their pricing is still a bit up there when compared to other offerings.
All that said, if you're looking for a BlackBerry Q10 on the cheap and don't want to deal with contracts or any of that, 1Sale just might be able to help you out. Right now, if you head on over to their site you can big up a factory unlocked BlackBerry Q10 for $400 outright with free shipping.
The specifications for the listing do show it has support for Quad band LTE 2, 5, 4, 17 (700/850/1700/1900 MHz), Tri band HSPA+ 1, 2, 5/6 (850/1900/2100 MHz) @ 42mbps, Quad band EDGE (850/900/1800/1900 MHz) meaning it should fit most peoples connectivity needs however, there is always the chance that may be just a generic listing they tossed up there, there's no real way of knowing.
As always with these sort of listings, some level of customer caution is advised. I've not personally had any problems with ordering from such places but there's no shortage of folks out there who will tell you otherwise. Also of note, the site does say it will be 1-2 weeks for shipping.
