Thanks for all of your help, I decided to buy it & negotiated it for $200 for the Cunill Brazil grinder AND the Expobar 2 group machine. I just feel like it's a deal that I can't let get away. Actually, it was Milow's post-link that inspired me to try and do an overhaul (his Brasilla post). I know it's going to need work, and it means that it will be installed in my roast shop, at least for now. Will need to run 220 and water (temp install for now), and as long as I don't electrocute myself or cause a flood I should be in business. Maybe after the rebuild is finished, and if it cleans up nicely, I'll be able to move it into the kitchen. Same goes for the Cunill.
I know that this is going to be a project that's over my head, I have no experience in, no manual, and not a clue, but I'm figuring that there's plenty of good advice floating here to help me through it. Once I get the A/C and H2O plumbed, I plan on starting a rebuild thread to track it's progress.
