Richie:
There are advantages to having the correct basemap for the area that you plan to use the GPSR in.
The issue of which GPSR to buy - Americas version at a lower price, but with a North American basemap, or European version at a higher price, but with a European basemap - has become a bit of a political one.
I don't have any opinion on the politics of basemaps, retailing practices, etc., however, you should become as well informed as you can on the basemap issue (the advantages / disadvantages of which basemap to have) before you make your purchase. Then, you can achieve the balance you want between economy and performance.
There have been a few threads in the past few months in which basemaps have been discussed. Here are two of them, for your reading info:

Basemap Theories...
Go through these two, after reading them you should be pretty well informed and able to make the best decision for your needs.
I don't know very much about the 60 series, what the capability of it is, etc. so I can't add much to what Adam has said. I think Adam is the resident SME (subject matter expert) on the Garmin 60.
