GPSMap 276C or Street Pilot 2610?

I'm trying to decide between a 276C and a Street Pilot. Seems the 276C is
pretty useless as it comes with no card, city or marine maps or speaker and
it's more expensive. By the time you've bought all of that, you're about
$300 more than the Street Pilot with only 128Megs of storage. Seems like the
Street Pilot is better value. What am I missing? Can I load lake maps into
the Street Pilot?
