You might just be the next Auber Instruments, Tony!
With some creativity and know-how, anyone can build a better mousetrap! While I'm personally very happy with the Auber PID, I certainly wouldn't be opposed to looking at more capability - as long as I don't have to build it!
I can, mind you, but my time and patience for that just aren't what they used to be. Off the shelf, proven technology for me, these days.
Good luck, and keep us posted!!
