brand new for $100, doesn't sound too bad. that same size Kenmore chest freezer is like $170 or so. normally I always suggest at least 7.4cu but even though its some off-brand, it sounds like a good deal.
The dimensions sound right for 2 cornies and a 5lb cylinder, without requiring a collar. it should also hold a bucket or carboy for lager brewing. and the ledge should hold at least a half case of bottles.
