Ran across this today: http://www.bestbuy.com/site/Garmin+-...ref=25&loc=PGR. Although the unit has lifetime traffic updates, lifetime maps are not included in the $79.99 purchase price. From the reviews, only three or four of which seem to include experience in Europe, several are positive while one says the European maps didn't work at all.

For someone looking to buy a cheap unit for basic navigation in Europe for an upcoming trip, this might be an OK option. The lack of liftetime map updates for both the US and Europe, although understandable given the low price, certainly limits its usefulness after about a year or so, however.
