I have this one. Great size. Never could find a small frost-free one but I've manually defrosted freezers with a hair dryer in about 10 minutes tops. When a chunk starts to come loose, I just pick it up and throw it in a bucket or sink. Dry with a towel and put the food right back in. The walls don't really warm up very much this way. BTW, manual defrost doesn't dehydrate your frozen foods so they'll last longer.
