I started out with a rev 1 and it was noisy and the metal pegs on the baffle broke and had to be replaced twice. Then it just didn't heat anymore.
My husband talked with Ian at Chocolvision, sent my rev 1 in to be service and it was basically totally rebuilt except for the outer plastic casing. At that time, they had a Rev3210 that had been sent in for exchange. My husband paid for the repair, & got 3 bowls and 2 lids, all for about $900 or so. I am EXTREMELY happy with this machine! It is definitely a world apart from the little noisy REV1. Please do not write off Chocovision machines. You should call and talk to Ian about your machine and I imagine he would give you great service as he did for us.
Really, the 3210 has made my life so much easier, no problems and every time I use it I am just so thankful that I own that machine. I can obviously get a beautiful temper with high quality chocolate (I use El Rey) but I have also been able to temper the pound plus bars from Trader Joes and use it for molding.
