Any time you need to go online looking for information regarding a product, because either you are having problems with it or you are looking at possibly buying something in particular, where do you go?  We all try to find review sites that can give us an idea about what customers in general think about particular products.  That said, I would like to recommend to you, if you are looking for any GPS device, that you go to gpsreviewsblog.com.  They provide a nice selection of product reviews that are all reviewed by actual customers, which will give you a clear picture of how good different brands and models are.
