Buying old control system parts

If anyone has any suggestions to this, let me know!

If you can not manage to get one from a team with all the parts you need: I got mine from eBay. You are possibly looking at $600-$1,000 dollars for the system.

Keep in mind you need quite a few parts not just the cRIO and modules. You need the module 'bumpers', the digital sidecar, the speed controls, power or the PDB and a WiFi AP.

If you do not mind the difference from FRC I also strongly agree the Arduino or an Intel Edison in the Arduino carrier board as a great alternative. Just keep in mind that reading encoders at high speed may be a bit tricky without some additional digital logic. There are IC for this or use a simple programmable logic chip to make it work.

Depends, what do you want to do with it?

I'm using simple RC controllers for robots and it's actually kinda nice.

I've also got a Gorgon sitting around that I'm hoping to use in prototyping some stuff this Christmas.

The FRC control system is nice for what it is, but it's not really cost effective. As far as PD systems, you REALLY don't need the FRC PDB. Look at automotive breaker panels (that's what FRC used years ago). Just don't skimp out on having breakers.
