As mentioned by gokfar, I really look forward to the ergodox group buy
It should roll around before the end of the year, group buy happens at http://geekhack.org/index.php?topic=22780.0
As for layout, I suggest Colemak with a custom alt layer such as http://forum.colemak.com/viewtopic.php?pid=5001#p5001
If you compare Workman and MTGAP 3.14 (shown [here](http://mathematicalmulticore.wordpress.com/the-keyboard-layo...) using [my keyboard evaluator](https://github.com/MTGandP/Typing), MTGAP 3.14 performs better on every single statistic except finger work. (You can see all of the different statistics explained on [my GitHub page](https://github.com/MTGandP/Typing/blob/master/Fitness). I didn't post them all here because it takes up too much space, but if you want, you can pull the program and to the comparison yourself.)
But the layout is just one of the problems. The key staggering is also not very ergonomic. There are two cool keyboards featuring symmetric key positioning:
