A new MR-C3024 costs around $200, though as they go obsolete, you might pick one up cheaper.
If you want to buy a controller, I would drop the 17th servo and go for an alternative 16 channel controller, which are more common and physically smaller
If you want to build it, the schematics and code are in my file area.

The MR-C3024 is basically am ATMega128 with pins and power supply. You will need to clock it at 7.3728 Mhz to be compatible with the Hitec software and add the EEPROM to store the Robobasic program.
Power supply and serial I/O you can do as you want.
The AtMega128 is available on a number of header boards, which may be suitable from Sparkfun, Olimex, Siphec. Or just use any adapter for the QFP package.
You will need a programmer to get the bootloader into the chip and set the fuses.Statistics: Posted by i-Bot — Thu Aug 05, 2010 10:44 am
