Looking to tinker around with a siphon and possibly incorporate it at work. Would like it to work hot as well as cold. Seems like the ISI gourmet whip is the leader but is pretty spendy considering I would like to have both a pint and a quart sized unit. Have any of you fine people used a Mosa? The stainless one looks very similar to the ISI and costs a bit more than half as much. Do they hold up and work with hot liquids like the ISI gourmet?
