I bought a Logitech G700s the other day... my favorite thing about it is that you can remap the buttons to any key or macro, has 5 profiles, and it has onboard memory, so you don't need to install the software on other computers to use them. So, I have a "gaming" profile, a "normal" profile, and a "work" profiles, and on my work profile, I have Ctrl, Meta, Alt + F4, Ctrl + c, server addresses and whatnot that I use all the time mapped, and it has been awesome--has really augmented my HHKB. In gaming mode, the battery life absolutely sucks, though.
