I like the BatteryMinder charger/maintainer/desulfator from Northern Tool. Priced a little more but has worked great over the past 4 years. Not a failed battery yet.

 

I got a Battery Tender Junior off Amazon today for $23.

 

I have a CTEK that I bought on amazon and am very happy with it. Have the pigtail hidden under my seat and it has a waterproof cap attached. It is orange and black so just get a sharpie and make it all black, disappears.
