Sosha,
Last time you asked about HT and regretted asking after seeing my answer
I have Expobar III R for a three years now, plumbed in, dual boiler, rotary pump, E61, PID.
This is great machine, capable of delivering much more than I will ever need.
It takes some 45 minutes to heat up.
Quite ugly if compared with similar Bezzera machines though, but you get used to it.
Never had a problem with it, except a bit of a leak, but it was caused by high pressure of my erroneous reverse osmosis system. Ever since I switched to the bottle supply, not a drop anywhere.
Also, because it has copper boilers, it should not be fed directly from RO system without re-calcification to keep acidity of the water in check.
Lastly, I would buy it again, and recommend to a friend.
Please let me know if you have any more questions. There is very good google user group with friendly crowd.
Regards,
Miroslav
