I use Colemak (<a href="http://colemak.com/" rel="nofollow">http://colemak.com/</a>), and I'm up to about 70 WPM (measured at typeracer.com, not anything more scientific). Unfortunately, I did no QWERTY tests before switching, so I can't compare, but I doubt I was significantly higher.<p>I'd recommend it. There are a few modifications I'd make, but overall it's quite nice. They've written programs to check finger travel distance, and it beats QWERTY and Dvorak. A reason to choose it over Dvorak is that it keeps WAZXCVB in the same place, so those common Ctrl-keys are just as easy to press.<p>There's several versions for Windows, including one that can be run off a flash drive, and work without installation (<a href="http://colemak.com/Windows" rel="nofollow">http://colemak.com/Windows</a>), and Colemak is also built in to X on Linux.<p>Although depending what you're doing, switching to an alternate keyboard layout can be a problem. For example, if I were a sysadmin, going around to different computers and fixing them, it would be infeasible to switch, unless I put the time in to being able to context-switch my brain quickly, so I could touch-type both.
