Hate my surge brakes -- want to convert to electric

Ok. I'm getting a little sick of my surge brakes. They need continual maintenance, caliper is sticking a little and so likely need to be replaced. I had the entire system replaced 2 yrs ago or so and I am still having issues.

So, rather than spend another several hundred dollars fixing this system, what do y'all think about electric brakes on my freshwater only boat trailer? Most of the folks online that have switched say its the best thing they have ever done. There are a few nay sayers who are afraid of something sticking or getting corroded in the marine environment. That may be true but I have pretty serious doubts as to how well they are working now.

That being said, has anyone done this? What has your experience been? Any brands I should avoid? Any info on this conversion appreciated

Thanks
