I ended up getting the Magellan unit.

I brought a printout of the a bunch of internet prices on the thing, which ranged from 306.00 to a tad under $350.00. CarToys flat out said they don't pricematch internet sites (which is actually contrary to what their web site says) so I took my business down the street to Best Buy, who said they'd give it to me for $349.00 based on the Buy.com price. Which is impressive, considering that's 50 bucks off.

I played around with it a bit this afternoon, and am happy with the purchase. Some nice features, a decent user interface. Perfectly usable.
