What's your plan for the machine, is it going to be a keeper or a flip,
if a flip like Glen said just a cleaning new fan motor's and T stat
to insure you don't get a phone call a week or two later from the person you sold it to is now screaming in your ear about the fan or T stat not working.
IF a keeper use it for a year or two then plan on restoring it.
( to make sure you still want to keep it)
Right now the market is soft in the soda machine arena but I think
when it gets hard again these little Sq tops are going to be the next big thing.
They work great for rec room or man caves and if they look nice and are clean
the wife will let them in the house
and they do tend to get attached
to them
.
And you did great for $250 it a good looking machine .
