Battery tender recommendations?

[bldavis11]

I purchased a battery tender and love it. It's probably the best $70 I spent on the car. In hind site, I think that I should have purchased the 750 mA version rather than the 1.25A version. There just isn't much draw on the battery to need the extra kick, and I've got a security system on the vehicle.

I've never used or seen the cTek unit and wouldn't buy one. The BatteryTender company and plant are only about 75 miles from where I live and that means a whole lot to me. I'm sure it's a good product. Both are basically regulated switching power supplies. You could probably build your own for a lot less that one of these costs.
