i got a G19 through a promo at work, its pretty crazy and replaced my xkeys. There are plenty of 40% off Logitech discounts out there.

One of the nice things is you can program not only profiles lile most of these keyboards do, but dynamic anything ... literally changing the keymap based on whatever. 'every forth time i press the return key, pass backspace'. I almost have a good button masher throttle written for it that will limit the times I spam backspace per interval.

The G19 display is amusing, you buy it for the LUA interface however.

Not sure what you want from the zboard keyboard, i would cross that off the options.
