Razer has 50% off peripherals today. I'm not sure if posting the code will be considered spam, but it is BESTOFCES2013.
I picked up a blackwidow stealth (non-ultimate) for around $64 after shipping and can provide feedback when it arrives.
If you want backlight, you'd need the ultimate series. The stealth has a matte finish and brown switches vs. the glossy finish and blue switches of the standard blackwidow. Either one will run you $70 with the promo code, plus another $14 or so for shipping.
