You could check eBay for a cheap used freezer , Although there is chance you could be getting something that has an issue.Not tech related, but I bought another freezer. We've been hoarding (mildly) for years now; Rotating stock, canning veg, etc... and when I got the option to get half a cow, I jumped on it, without thinking first.
Then my inner self said, "hey dumbass... you have no where to put it!"
So of course I had to fix that and now I have room for almost 200 lbs. of various cuts of beef, 50 lbs. of chicken and 25 lbs. various pork cuts.
Now I just have to find a way to convert my garage into a temp controlled living space on the cheap. I'm out of room in the house.
