From what I've read a good Rockwell tester can be had for around $1000. The problem with them is that they need to be in a clean environment with consistent temperature and humidity. I've also read to beware of the used units that you can find out there, especially if the site says no returns, because they may be so old that the manufacturer may not support them anymore.

You also have to learn to use them right. They must have parallel surfaces and you have to be aware that shallow hardening steels can lead to erroneous readings if the piece is too thick and the grain is fine.
