PLC Options

Hi guys and gals;

I want to play around with a PLC program and I am wondering what are the best options. I have experience with Unitronics and Allen Bradley but I want to buy a few components of my own to play with and I was wondering what is recommended. I want something that offers a good colour touch screen display that will have a good graphic. Cost is a factor but will not sacrifice quality for cost, support/training is an asset and product availability is very important. I would like to have something that can talk multiple communications if possible (Bac net, Can bus, Mod bus, Profi net) and user friendly would be nice too. What do you all recommend? Your input is greatly appreciated.


Thanks

Brad
