Had a chance to look at this unit this morning:
https://rochester.craigslist.org/app/5347137155.htmlThe seller, who seems slightly clueless about the unit, says he has had the unit for a few years and hasn't used it since 2013. Apparently it was owned by Genesee and he claims the co2 tank and beverage lines were "new" when he used it in 2013. He didn't realize he had the thermostat set on 1 instead of 7 (coldest). As a result the bucket of water was only 45f. I turned the knob as far as it would go and the compressor kicked on. I hope to test the temp again tomorrow. Obviously a deal breaker if it doesn't cool lower.
As for the rest of the unit, is in pretty solid shape structurally. The tower fan ran the entire time and wasn't super loud. It needs a good cleaning, is missing a thermometer, drip tray tube/collection vessel, and there isn't a functioning light, which I'm not positive these older models had to begin with.
The door seal looked ok but slightly damaged at one of the corners. It may need to be replaced. The regulator is pretty knicked up and will almost certainly need to be replaced, as will the beverage line and likely the co2 tank.
The seller has not ever done a refrigerant re-charge and doesn't know if one has been done. It uses r-12 refrigerant, which while not ideal, I've read isn't a major issue.
I also noticed that it did have a blow hose for the air cooled tower, but it looked pretty nasty/possibly moldy.
If I go tomorrow and it is <<38f (I assume that 5 gallons of water should be somewhat frozen at the coldest setting), I plan to make an offer. In light of what I stated above, do you think a starting offer of $200 is offensive for a unit listed at $400? I will not spend more than $300 and I will likely need to pump a few hundred more dollars into it in the near future.
