I have a Bibby from the UK. I bought it because I'm in 230V land, and it was big and relatively cheap. No problems with it so far, and I can easily do a 3-4 liter extraction at a time. I've been using it for all kinds of things like making yogurt, water bath for agar bottles, candying fruit, and what the hell ever else. I love molecular gastronomy, which is a good alternative use for all the lab equipment I have in my kitchen.
