For this location I am going to stick with the old CM11A and the original Pro. It works well. I just installed the Booster/Bridge and everything seems to be working perfectly. I want to fiddle with it some more...
I just ordered a cheap "guaranteed to work" $3.50 USB to Serial cable and software from eBay... if it doesn't work, the person promises to make good... so we'll see.
For a different location, once I'm certain that the CM11A is solid, I'll likely go with the Pro.
We'll see.
Just wanted to say thanks to all that helped!
