Need some advice on bilge pumps. #66 came with one of those long hand pumps (looks like a bicycle air pump), but it seems to be terribly inadequate to me and I certainly wouldn't trust it in an emergency.

Can anyone recommend any particular brand/model?
How about size?
Dealers where I can find it/them?
Configurations:
--I've read in Good Old Boat about using a large electric supplemented by a smaller one, but are electric pumps really necessary?
--Where do you put a manual pump? In the cockpit? Near the bilge? One in each place?
--I've read that you should never put one where you have to open a locker/door/whatever to use it. If that is the case, would a cockpit-mounted pump have to be out in the open and in the way? Can a pump be mounted out of sight with the handle easily reached?
--Are there bilge pumps that can be foot operated?
