I thought you meant something else in your title. I bought a chest freezer off Craigslist for what seemed like an absolute steal - $40 for a perfect-sized, late-model, Energy Star.
It was quite a bit of a drive, but having already tried for a couple months to nab a decent freezer off Craigslist (for even TRIPLE the price) and having ALWAYS gotten beaten to the punch (over a dozen times DESPITE calling within a half hour of each ad being placed), I headed out there the moment I got them to promise to hold it for me for at least a few hours (so that I wouldn't waste a fairly significant amount of time and money getting there only to have it sold out from underneath me).
I mention all that to explain why I still decided to buy it when I arrived to find it sitting in their VOC-stinking garage with the lid open and a fresh coat of paint (actually, crappy interior-grade white primer, I believe) on much of the interior surface, which was NOT apparent from the picture nor the wording of the ad. I wasn't sure if it was just the lighting or what, but it seemed to have a faint blue-green tint to it. Also absent from both the photographs and the wording of the ad was the fact that the original feet or casters were removed and it was instead permanently mounted on blocks of wood, and any indication of the dangerously shoddy rewiring job by the compressor that both "spliced" a bare copper wire AND insulated it with (what appeared to be) super glue!
I took it anyways (after knocking it down another $10), because I didn't want to go home with nothing to show for the trip. I should have known something was up when initially getting the directions from the guy's wife, when she told me her husband could be talked down to $30. Apparently she didn't even want to RISK having to keep it!
Anyways, the girlfriend at the time insisted I leave it in the garage because she too was worried it was full of cockroaches. There actually ended up being a "bug" problem indeed, but it turned out that the reason they painted it was apparently to cover up the mold and (with some bondo) rust. Probably wouldn't have even been a big deal if I was going to use it as an actual freezer, but the considerable amount of condensation that inevitably built up (even with Damp-Rid and a fan to properly circulate the air) made it an utter disaster, and the brews that I had put in there (and the ale pails that contained them) didn't stand a chance!
When I moved out of the place, I was offered me $50 to just leave the freezer there, which I accepted AFTER making them aware of its issues (and I had properly repaired the wiring, so I wasn't passing a fire hazard on to someone else). Without any exaggeration, I would have paid THEM $50 to not have to haul it out and deal with the POS myself... good thing I hadn't tried to work out something else with them first!
And there is a happy ending to this story. My next ferm chamber was/is going to be an "expanded" minifridge - basically removing the door, butting the opening up to a wooden frame, sealing and insulating it, and mounting the fridge door (separately) as the access to the interior. The top of the "frame" will function as a work bench/surface in my man cave, which I really needed anyways, so it's an amazing use of space. The "happy" part is that I ended up getting a *perfectly*-sized and very modern and attractive black mini-fridge, only a year old and without a single scuff, dent, or scratch. For FREE. From a really nice (yuppy) family off of Freecycle. They really liked the use I had planned for it and were apparently able to separate me out from the dozens of hoarders/scrappers/resellers you'd expect to see respond such an ad. ESPECIALLY considering that people on Craigslist around here ask for nearly retail prices for mini-fridges that are actually in fairly poor condition. The whole experience with the amazing and generous family on Freecycle really contrasted severely with the greedy, unscrupulous family (essentially) scamming others into buying their garbage on Craigslist.
