So I have a hobby project I've started planning. This won't be in a very harsh environment, so I was kind of thinking about using a fairly cheap PLC and a standard computer with a few modifications to do the controls. There also isn't much potential for danger in this equipment.
I was thinking about using something like a Pi or Ardunio for the project, which would work fine but I would really rather have something that was, in general, packaged a little better.
We have some Modicon OTB's with an RS485 interface to a computer do that do some minor controls stuff at work that are pretty cool. The problem is that they are around 400-600 each for a basic device, and that doesn't count the computer or any of the field wiring/devices.
Do you guys have any suggestions for something similar to this:

I would really like something cheaper, but it doesn't necessarily have to be all that robust. Analog IO would be pretty useful too.
