At Best Buy we got a brochure of all the Garmin products, very helpful. I personally have a Nuvi and love it because of the convenience of putting it in my purse or pocket. The Street Pilot is much more cumbersome. The Nuvi is more expensive but has more features. The brochure or going to www.garmin.com will give you alot of info. I found the best price at Amazon for my Nuvi.
