"AB may be better but it is not 5 to 10 times better as the cost would suggest."
I have NOT found Allen-Bradley to be 5 to 10 times as expensive as other brands. Siemens is every bit as expensive as A-B. We haven't used Modicon in a long time, but when we did there was no significant difference in price compared to A-B. Mitsubishi and GE Fanuc are also similar in cost. In fact, I've never run into ANY PLC that apples-to-apples is one-tenth the price of A-B.
Granted, there is a premium for A-B. That premium is very similar to the one for other "Tier 1" vendors like Siemens. AutomationDirect.com does have $99 PLC's, while a full-blown ControlLogix could run $10,000 or so. That's a hundred times more expensive! But it's not like comparing a Kia to a Cadillac; it's comparing a motor cycle to an 18-wheeler. A-B also has a $99 PLC.
