Thats what everyone says. But i got the 450t and i also downloaded some of the free "high quality" maps,and to be honest i haven't found any free ones that i like better than what came on it.
The 450t doesn't come with street maps; it comes with 100K topo maps. If he wants street maps he will still have to buy/download them for the Oregon 450t.
I agree that the 450 is the best choice for the money.
