I live in S FL and have numerous electric blankets (it's 40's today!). My fingers are like ice when it's below 70. My husband isn't always cold like I am so I have a twin sized electric blanket folded in half under the fitted sheet on my side of the bed, works perfectly. I also have a heated shawl for when I watch TV. I prefer Sunbeam brand (I bought one from the clearance section at Walmart last week--they had lots). I had two Biddefords and both quickly stopped working, not sure if it's just bad luck on my part or the brand. Therapedic is also a very good brand, they are very soft and luxurious.
