Ridgid has free batteries for life (IF YOU REGISTER).
As for a drill for "3 or 4 times a year"... I really have no idea.
I will mail you an old Makita 9.6v stick type drill free (without batteries) if you pay the shipping... batteries are $20+/- on FleaBay. Great drills... if a drill/driver is all you need.
Drop me a PM if interested.
