BTW, I got a cafe rosto from sweet maria's and alsso a bunch of green beans (Christmas present from my wife). Alas, so far every batch I've roasted has tasted undrinkably bad. Not sure what I can be doing wrong, I've tried different batch sizes and roasting times. It's taking me a good 15 minutes to get close to a full city roast, so maybe the problem is that my house voltage is too low and it's just taking too long to roast? Any pointers would be appreciated ... and if it's the voltage, is there some kind of cheap voltage regulator I can put between the rosto and the wall socket?

Joe,
check out what SM has to say about this roaster:

Before we describe all the nice details of the roaster, be aware that this machine is highly influenced by the voltage of the circuit you plug it into. Yes, we are all supposed to have 110/120 v, but in reality when you measure actual voltage in your house it can be quite different. This machine really likes 120 volts or more, and not too much "volatge drop," meaning that once you turn it on the voltage doesnt go down to something like 108. Think of it as a big hairdryer. If you have a newer house or good updated electrical you should be safe. As with all electric roasters, do not use extension cords or power strips ... these usually drop the voltage. If you do have voltage problems, roasting dark with a Rosto may involve getting a Variac, which is a big expense.

It definitely sounds to me like you have too low a house voltage, or are using an extension cord. What happens if you wait a long long time? Do you know about first and second crack and what they sound and look like? This machine is a slow roaster, much slower than a hot air popcorn popper, so perhaps you have been under-roasting. Under roasted coffee does indeed taste vile, and sometimes the color of the beans will fool you and be darker than the actual degree of roast.
As for a variac fix, it's on the order of $100 from SM. coffeebeancorral (sp?) .com has a model for $50, but it is being way overdriven--they replace the fuses and everything. Safer to pay the extra $50 because you'll definitely melt something or other on this cheaper model. So it's a lot of money to remedy low house voltage.
Anyway, sorry Empath for the OT post. Joe, post in the Coffee thread if you have any further questions. Or PM me, or email sweetmarias. They are awesome at returning emails.
