Any suggestions?

I'm leaning towards the BatterMINDer particularly due to the following info they provide:

Why you MUST use an Aviation-Specific Charger!

An aviation-specific battery is different than auto or marine types. To maximize the cranking amps and reserve capacity, while trying to minimize weight and size, aviation battery manufacturers use a higher specific gravity (SG) electrolyte in their aviation batteries. This "hotter mix" (more H2SO4 [sulfuric acid], less H2O [water]) means it will be overcharged whenever a non-aviation charger is used. Automotive chargers are set at a higher output voltage (typically 13.8 -14.6 volts) than aviation batteries can handle. The voltage settings and charge rates for aviation BatteryMINDer® models have been chosen after conferring with leading aviation battery makers in the U.S. We are the only approved manufacturer of maintenance chargers for use on all Concorde Aviation batteries.

BatteryMINDer® aviation specific models incorporate a Plug 'n Run feature, and includes full-time, fully automatic pulsed desulfation circuitry (not high voltage) designed to safely dissolve sulfation build-up on the battery's storage plates, restoring lost cranking power, and extending life. They also feature a temperature compensating sensor to ensure that batteries can be safely charged and maintained for extended periods of time in extreme temperatures. Without this type of temperature sensing, batteries will be under-charged in colder temperatures, and over-charged in high temperatures.

Go with the battery MINDer, we use it on our r44. Works great and I've had no problems with it.

Likewise. We use Battery Minders on all six of our R22s, three R44s, and our four Bell 206s'. They work great. No complaints.
