Am thinking I need one of the stand-alone, wheeled jobbies, NOT a small plug-in unit such as the POS Black and Decker I just tossed in the trash. I want a heavy-duty/industrial one, I think, as I'm sick and tired of the cheapo, use it three times and it freaking breaks types. I need it primarliy to be able to charge marine and car/truck/motorcycle batteries, that sort of thing. Greatly prefer American made. Prefer the option of charging two batteries at once. Don't want to spend more than $500, but no problem doing so if that's what it takes to have a machine that does what it's supposed to, and well, for a lot of years to come.
Thanks in advance for any help.
