I just bought 4 Magellan Maestro 4370’s for my guys in the field. I was tired of paying extra for rental cars with GPS’s. Refurbished, they were $113, no sales tax and free shipping from Amazon. A lower end model, so it may not have all the bells and whistles some have. I just took a quick look at them so can only report what my guys had to say. 3 of the 4 worked flawlessly. Easy to figure out how to use and got my guys all around the Phoenix area for 5 weeks without problems. The 4th one tended to freeze up 1/2 a mile from the destination, so I returned it for a replacement unit. So far havent had any complaints about it.
My wife has been using a Magellan 4050 for about 3 years and loves it. Got me all over new england a couple summers ago. Other than confusion when I took the ferry from Long Island to CT, we became very good friends.
