This new project from KK is of interest to myself, especially if the end result is fine tuned, as it would be handy to have two roasters. I can see potential for slight improvements on my current unit. I have considered an electrical 1.5 to 2kg roaster, but have not been impressed with any that are reasonably priced. Spending over $10k for a home roaster would result in a very unhappy wife. The "bullet" is interesting, but has some limitations. I was informed that an electric roaster is in the planning stage by a reputable Roaster supplier. Due to his workload, I do not think anything will be launched or even at prototype stage in the next two years. For the cost, what KK offers is very reasonable, as $1000 buys very little these days. As to a power supplier for the agitator, look no further than your old cable or ADSL modem. With everyone moving to NBN and receiving a new modem, the old units are obsolete, but the power sources are still very good. I use one from my old cable modem, and find it is very reliable. The unit that came with my roaster had some damaged wiring, and was prone to cutting out, whereas its replacement performs perfectly, 100% of the time.
