The most affordable option in today's sale is this $40 625VA/375W UPS PC Battery Backup, down from its regular price of around $65, though this is the only model which doesn't mention having a Connected Equipment Guarantee. However, having one would surely be better than just winging it during a lightning storm.

If you are looking for that guarantee, any of the other options in today's sale include one, from the 825VA/450W Intelligent LCD UPS System for $58 that regularly sells for more than $80 to the 1500VA/900W Intelligent LCD UPS Battery Backup that's more commonly found at $145 rather than today's price of $120.
