Yes. Especially since nobody seems to believe me when I say it makes almost no smoke, or that it seems safer to use than other "approved" roaster which have a tendancy to burst into flame.

The BT probe seems to be placed very well in the bean bed. The drum rotates at around 60 rpm clockwise, and since the drum is rather small, with internal fins running all the way front to back, the probe stays well covered as long as you don't go below 150g.
The ET probe is also in the drum, but outside of the beans. It's rather slow to react since it's inside the thick, solid drum and just above the beans. Ideally, if you really wanted to see the the effect of heater changes, you'd place a thinner probe on the outside of the drum where the heaters are. Place at the top where the heat rises. This would be a more accurate MET (max environment temp) and would allow better control of the roast. As I have it now, the ET is really an average of MET and BT. And actually not too useful.
My Quest is a bit of an oddball I found out. It seems to be a one-of-a-kind "Canadian Edition" with a lower voltage (higher heat) 100V x 600W heater on the left and a higher voltage (lower heat) 116V x600W heater on the right. They did this apparently to give the heating a bit of a boost in case I wanted to roast outdoors or in my igloo.

I'm not sure how long the over-driven 100V heater will last at 120V. But at $20 each, if it goes, it won't be so bad. (I'm buying a couple of spares just in case).
I stripped down my Quest yesterday and I must say, this is the best build quality and most thoughtful layout I've seen on any coffee gear I've purchased. Kinda like my Cremina. The whole thing can be stripped with two metric Allen keys. Beautiful! In these days of disposible iPods and such, this is very refreshing to see.
