I picked up a Max Keyboard Blackbird during a recent sale. It's the only tenkeyless mechanical keyboard I could find with a built-in USB hub. The backlight is a nice bonus. The keyboard defaults to 6KRO. When I set it to NKRO (over USB), the OS X keyboard viewer showed as many keys as I could hold down. However, it no longer recognized the Caps Lock key as Control, as mapped in the System Preferences.
