Thanks for the responses guys.
I did see the μTRON in my searches. It looks pretty cool. But not enough thumb buttons for me. I've been using the Kinesis Advantage and really got used to using all of the thumb buttons for all the modifier keys, space, enter, backspace, etc.
I think I'm just going to experiment with clear switches and maybe try to make some "jailhouse blues" to see if I like that.
