Kinesis Freestyle Pro? I've got the non mechanical version (mechanical wasn't available when I purchased) and it's held up for many years. It's a great keyboard IMO.
The Freestyle Pro is almost a good keyboard. The Esc and function keys are all offset to the left by one key compared to a standard layout, which drove me nuts. I have a Freestyle Edge RGB now, which I like much better. (Though I replaced the wrist rests with some from Goldtouch.)
