I actually used this for a laboratory setup just recently, but I only  
needed about 1% of accuracy. I bought a "Arduino Duemilanove" board  
for *?25*. This includes a FDTI USB-to-serial and a Atmel AVR  
microcontroller and is powered from USB. Their simple IDE speaks a  
preprocessed version of C and it took me 5 minutes to have my  
3-channel-analog-to-serial software done. You can also use your  
conventional toolchain and just ignore their beginners' environment,  
though.
