yes, currently $50 is a decently good price (anything in the $40-45 range is a sale price and is rare)

either one will get the job done, the extra amps just reduces the number of hours it takes to do a full charge + conditioning.
I have two of these and they work flawlessly. I like the options for different battery types as well.
