I've been watching the Garmin Street Pilot prices for a while now, waiting for them to come down so that I can buy one for my car and travel. Today e-cost has the Street Pilot 2610 on sale for $349, which sounds to me like a terrific bargain, so I'm placing my order right now.

There are two newer models in this class: the 2620 and the newest (I think), the C320/330. Both are significantly more (700+), but I'm not seeing any major functional differences.

Can anyone who has one of these (or spent some time researching them) comment on the differences?

Much appreciated.
