I've been using an AeroRost II (same website) as my primary roaster for over two years, more or less happily. It's basically a George Foreman electric rotisserie oven with a halogen heat lamp to increase the roasting temperature. The Micro Tosta Caffe (gawd what a name) appears to be a slightly beefed up model. I wouldn't take the website info as gospel, but drum roasters do take longer for larger batch sizes.
The AeroRost easily handles 1-1.5# in under 20". You can roast 2# or more, but there is a definite risk of fire (this has happened to me twice). Nonetheless it's been a nice combination of ideal batch size and convenience, especially in winter, when I can roast in my fireplace. If you're interested in the Aerorost,
get the stainless steel drum upgrade. Perforated aluminum sheeting melts.
IMHO electric rotisserie ovens have great potential for home coffee roasters. The Behmor 1600, a new 1# roaster based on a Ronco rotisserie oven, recently took Best New Product at SCAA. Feature-laden for the price, it's been the subject of much discussion on CoffeeGeek and other coffee-related fora, and should be coming out Real Soon Now. Anyway, nice to have alternatives to the 1/2# Bravi, GeneCafe and Hottop.
