I use a Parker L25i intelligent stepper drive. They're modular (plenty of room for expansion if you choose the correct power supply), use RS232 and can also store their own programs, which I find really handy for repeated moves. They're not exactly expensive either, and they can even be DIN-rail mounted for extra industrial appearance.
They come with their own terminal-type program which isn't worth the hassle if you want to do any serious programming. Figuring out the command format to use it with VISA isn't too hard though with the likes of Portmon. I have done that myself, and I have VIs that can control the thing which are in development.
Hope this helps, Steven
