I believe the one that is available from BMW is made by these folks. I have a the CTEK Multi US 3300 .
They also sell a comfort indicator with eyelets that can be connected to the terminals under the hood permanently and simplifies hook-up.
I think it will still require you to pop the hood because the leads are not long enough to reach the radiator grill.
