Hi Laurent, I have the motorised version of the baby roaster, and have to say it is a joy to use. I installed a s/s hose clip inside it to act as a stirrer arm, and shake the beans about every 60-90 seconds. It is a lot easier to use than the manual version. I would recommend this unit over the behmor, as you have so much control. You can play with different roast profiles and gauge the best one to use for a particular bean, or blend. It is a fantastic sample roaster which would compliment the KKTO. Roasting times are quick, 12-15 minutes, plus a couple of minutes to cool the beans. You can start again, straight away. It is compact and easy to store. I roast in the garage, as it provides perfect shelter, but leave the door open for the smoke to escape. Maintenance is a piece of cake. Batch sizes can go up to 230-240g, but it depends on the beans. I tend to roast soft and hard beans separately, as I prefer my Brasil and Indonesian beans roasted to a particular level around second crack, but the harder beans benefit with a bit more depth. I try to avoid the huge cocoa notes in my coffee. Recently, by choosing the correct beans, I roast 3 and 4 bean blends together and get very good results, so my roasting skills must have improved a little. The beauty of the baby roaster is that you can use the beans straight away, though they do benefit from a rest. I have been caught out a few times recently, and was surprised how nice the coffee was, one day post roast. Call Mark from CRA and have a chat with him about the unit. He is very honest with his replies. Downfall with the unit is the batch size, as I believe 300g would be ideal. There was a rumour that a new version was on its way, but it might still be a while before its release. Either way, enjoy the experience.
