I would guess it was a comprimise. If you assume your design is 100% on/off then you'll need to size your elements for your application. At 1000 watts, it's a bit over kill for 1/4 pound, just about right at 1/2 pound, and a bit under sized for 1 pound.
If your electronics could vary power to the elements then you would have more upwards mobility to over size the elements and reign them back.
Another consideration is the afterburner. With the 550 watts it consumes + the 1000 of the elements you are starting to get close to the limits of some older house wiring.

I only roast 1/2 pound per roast. I would love a faster ramp-up but more importantly I would love an on/off switch for the heat elements. I could live with the P1 program if I had the the ability to control the heat between 1C and 2C a little better than what the default programs give me.

All we ask for is a roaster we don't have to fool with to make it work as it should. You don't have to forfeit built in safety to have proper function.

I don't think it would help too much. It's already fairly tight in there after accounting for the drum. If they released something redesigned I would think either higher powered or a third element that can all be controlled would be best. If they don't redesign I'd prefer to see a more thourough preheat allowed. I think the safeties are a little too tight.

Joe,
>snip< Should I need a part one day I'd still like to be able to come to you and BUY (I fully acknowledge that I can't expect WARRANTY support) it and do business with you. I don't like the way you've discouraged this conversation however and I really got the feeling that you are pushing some scare tactics here with the legal stuff. >snip<
At least you can still BUY parts from Joe. Not so with the 'Mental Ware Company' (Nesco)

Oooh... 3kW instead of 1.6kW. The Behmor 3000! With MANUAL element control!!!!
:D
We could do probably a lb with no sweat, maybe more... I've always thought that it would be great to be able to do 575g of green, 1C at 9:00. Then you could have a home roaster that YIELDS 1 lb of roasted coffee per batch.
The Behmor 3000M/1Y (3kW heating, manual element control, 1lb yield)... ;^)

"There is no right answer with coffee. There is only the elixir in your cup at the moment you partake."

Or you could give up the afterburner. That'd be fine for people that have ventilation or roast outdoors (I'd be ok with that!) but for some people that roast indoors that might not work.
I think a case can definitely be made however that even with the afterburner at 1 pound it's a little much for indoor roasting.
