Phil,
I agree, there is no equal to Cooperstown. It is hallowed ground as far as I'm concerned. Quick note about Springfield compared to Cooperstown. Go to the hoops HOF but don't expect to walk leisurely around and enjoy the neighborhood like Cooperstown. You will know what I mean when you get there!
They have helped folks a bit by having a walking mall with food court as part of the basketball hall of fame so you can eat and shop a little right there without having to go outside.
Have fun. Nothing better than a road trip!
Peace, mike
