I think the HDS-5 with the base map is running just under 800 bucks. So with the sale and the rebate it would be about 700. I bought my HDS-8 when I was in the States for hundreds less than I would have paid in Canada. If you know someone in the States there are deals to be had, but shipping kills most deals. It can be had for $649.99 minus the 50 dollar rebate here...
