I feel your pain. I started looking about 5 months back. Bought one is Seneca SC for $75 and it was huge. SWMBO hated it and I really didn't need one that could fit 9 kegs (but honestly, if you have space and a love for brewing...go big or home). Then i looked around and had 2 available in Charlotte (where I live) for $50 and they were prestine. But got sold right form under me when I asked for dimensions and such. Luckily i found one in Florence (great condition for $50) and another one that was older but work (now my fermentation chamber) for $40.
But now I am helping my buddy make one and it seems freezers have risen in value. Can't find a 5-9 cu ft freezer for less than $125 anywhere. At the time, $50 freezers riddled CL, now they are unicorns. If you do the math and think a decent deal, you gotta take it. Price gas into the equation, but also be smart. Some crap is on CL, and you can't return it.
What's your size and price range. I do a scout out in Columbia/Florence/Charlotte/Greenville every so often for good deals. I will be on the lookout. My buddy is wavering his kegging commitment, but i like finding deals. Sold the giant freezer for a $25 project and a happy SWMBO. Also I have found some 20 lb CO2 tanks for $20 each (wasnt quick enough).
