I am looking to turn a chest freezer into a lagering/cold storage chamber and I found a 4 year old used haier HCM071LC on Craigslist for $75 in what appears to be decent condition. However, someone told me that chest freezers in general are pretty unreliable and for that reason I should go with a new one. Does anybody have some input as to whether there is any truth to the idea that chest freezers are unreliable to the point that buying one used is not a good idea? Thanks so much!
