Insignia is Best Buy's house brand. Might be worth looking into the specific model your looking at to find the actual manufacturer, and see reviews of the equivalent model. I have an Insignia tv made by Samsung, been great and was cheaper than the Samsung branded model.

 

My wife spent several weeks looking for a new freezer. She said that if you contact the smaller appliance stores they can let you know when they come in. My old freezer was a 1985 module ran continuously till a few weeks ago. The seal was leaking from the door which had become off kilter making it Ice up too fast. Got my $ worth from that one.

 

They are tough to find. We have 2 months left on a 31/2 month waiting list to get the one we wanted.
Based on my experience and research stay away from LG and Samsung.

 

Not sure how desperate you are, but there're a few on Craigslist.
