After doing a bit more research I must say the sensored/sensorless "hybrid mode" of the Tekin RS Pro seems like a useful feature. I'm also tempted by its HotWire system, as I love everything that can be hooked up to a PC ;-)
I thank you all again for your input. It has helped me to get an overview of what options I have, and I'm now pulling back to make my final decision
Thanks
Tom
