Where did you find that deal, if I may ask? The cheapest place I've been able to find the 60cs is Amazon.com. I checked the price on the 76cs after reading your post and it was considerably more expensive after figuring in the City Select software. The gps was $521 and the software $107. I'm curious if the place you found your deal would have the 60cs at a good price as well.
Sorry, I didn't notice your post until now.

And they extend the warranty another year
Hope this is permitted (haven't seen many references to vendors) but I find the best prices for Garmin GPS's at www.gpsdiscount.com. I've purchased two GPS's through them and will purchase a third shortly. In addition to the lowest price they throw in a free T-shirt. Additional hint: if you have the unit sent to a business address your either get a break on the shipping cost, or you get quicker delivery at no extra charge (I can't remember which). However, some accessories are as cheap or cheaper on Garmin's site. I'm aware of four GPS's being purchased from gpsdiscount.com and they seem to have very good customer service.
