The prices continue to come down for the machines and if you use any service bureaus for rapid prototype parts the prices have really fallen in the last few years. I order SLA and SLS parts all the time for my industrial design business. I still wish the material properties and resolution were better especially when designing injection molded parts with tight tolerances. But it keeps getting better each year.
I also have a "drool tool" ... a benchtop CNC machine with 19"X, 7"Y and 5"Z travel(plus you can move the Z axis manually to handle taller parts in steps). I design parts, usually in Rhino, run them through Visual Mill CAM software and cut them in Foam, plastics, alum., steel, whatever. Following is a link for the CNC machine and under the testimonials tab there is some work I have done (btw, I have now owned the machine for 2 years, not several months stated in the testimonial)
