I have two freezers which may suite your needs. 1 is an upright and one is a chest. The upright is around 20 cubic feet and the chest is 16 or 17 cubic feet.
The upright was about $650 if I remember correctly, it's frost free and is 3 years old. The chest was around $500 and is not frost free. I got the chest from Lowes or Home Depot 2 years ago. Both are in very good condition, no abuse, they just sit in my garage and have food in them. I'd be willing to part with one of them, either one suits my needs just fine. We can negotiate a good price for either.
