I have had a small unheated ultrasonic since 1999. I got it, very well used, from an orthodontist buddy. I typically fill it with boiling water from a kettle, and add a bit of dishwashing liquid, usually something like Dawn that is really good at cutting grease, etc. It will just fit one carb body at a time, and has worked really well.
It is now on its last legs (I have repaired it twice now) and I have been day dreaming about acquiring a large powerful unit with a heater. Something like this

that particular one is more money than I would prefer to spend, especially in USD and with shipping costs. Can anyone suggest a decent quality large unit? There are all kinds of parts that can benefit from a dip in an ultrasonic, after an initial dip in the de greasing solvent tank.
