Morning Mark, don't take this the wrong way, however I guess it depends largely on whether your a coffee freak or a technophile.
My ultimate goal is quality in the cup and achieving it the simplest way I can.
I roast 750 grams of green beans (very successfully) about every week to 10 days, and have been doing this for many years.
The only reason I'm explaining this is to give you some insight as to where many of us on Coffee Snobs are coming from.
There are certainly those among us who are into the technology as well as quality, however I suspect the majority are aiming for quality in the cup in the simplest/easiest way it can be achieved, I know I am.
FWIW here's a pic of my first roasting efforts, pretty low tech but the result was good, from this I graduated to a Coretto, and, have stuck with this method to the present day.
