In real-life terms, a faster crystal means things execute faster - including delay() and milliseconds() - as well as serial I/O. If your software doesn't rely on time, you should be OK. (If you're debouncing buttons, you might want to increase the time by 20/16 to compensate.)

You can use a Uno to program and then move it over to your faster crystal board to run if you don't want to bother finding a bootloader that handles 20 MHz.


Back to the OP, there is a product called the RBBB arduino sold as a kit by Modern Device.


It probably represents the practical minimum you can take an arduino down to without hitting problems.  A lot cheaper than a Uno but you need some form of external USB-ttl adapter to program it.  Quite fun to build even if you're a noob with a soldering iron.
