I'm a lover of Kenmore. My mom has a chest freezer by Kenmore she bought 20 years ago and aside from the lock/handle combo part coming loose (the lock holds it on, but the handle part turns around the lock) that bad boy is still working like it's brand new.
Depends on how much of a 'stocker upper' you what size you might want. 14 cu ft is a pretty decent size freezer in a chest model (if it was upright I'd definitely go a little bigger). One thing to remember ... freezers work best and most efficiently when they are mostly full. If you know you can keep a larger one mostly full most of the time go for it ... if not stick with the smaller one.
Everyone I know who has had kenmore has had them last 15-20 years.
But I think most of the more well known brands would be good. I just have the most experience with Kenmore.
