Thought someone would have replied to your query by now. Guess everyone's hunkered down for the weekend
The ProMariners are OK, but they are very noisy from an RFI perspective (interference with HF radios).
The Charles Industries chargers have a good reputation, but I've no direct experience with them.
MasterVolt chargers have a good rep, too.
The VICTRON Energy chargers are terrific. Probably the best-built ones on the planet. I've got a MultiPlus inverter/charger and love it. Have installed several others. A friend has three of them on his 60-footer! Only problem is that Victron products are expensive (and, yes, you get what you pay for!).
I'd steer a wide course around any Xantrex chargers. Many problems reported and customer service virtually non-existent.
Best bang for the buck...especially with flooded batteries...are the Iota chargers with the IQ-4 smart-charge option. They're very well designed and built and work extremely well. Very good prices, too, from Arizona Wind and Sun, and other outlets. They come in sizes from 15A to 90A. I've got two (one at home, one on my boat) which have been in use 24/7 for nearly five years.
