+1. Garmin Montana 600.
I got the 600 because all the 650 offers is a crappy 5mp camera which is useless, and while the 650t comes with topo maps pre installed, you need to have it plugged in when using basecamp.
Speaking of which if you get the Montana be sure to factor city and/or topo maps onto the price because they don't come pre installed.
It's a great GPS though.
Here it is on a RAM mount, I've since installs it centered on the GSA bar with an SW-motech mount.
