Save $30 with coupon at checkout. Is listed at $64.99.
The Z88 has decent reviews and the price pushed me to buy one more keyboard than I really need. But it's vital to have a spare.
For me, deciding factors, after the price, were the number pad, that you can choose solid colour lights, and blue switches (my preference, and I don't care who has to listen to it).
As a bonus, maybe, are the metal frame, otemu switches (don't have these, I think) and hot swappable keys.
Price with coupon is keen according to camels.
Just be wary that Outemu hot-swappable keyboards are usually only compatible with other Outemu switches due to the pins length being shorter than standard switches.
I learned this the hard way when i bought the Tecware Phantom keyboard.
