Oh my, we get lots of calls requesting me to make a choice for folks so that they don't have to decide which GPS unit to buy.  Looks good on paper, but how can I know which features might be really useful or totally useless to each individual person.  I could just decide which GPS unit I might prefer, but how would that information help a total stranger whose needs and budget may be totally different from mine?  I feel like I really disappoint people when I try to point this out, but we are all individuals, which is why there are so many different versions of, for instance, handheld or automotive GPS units out there. 

Most of the manufacturers, especially Garmin, have really great interactive websites already where you can choose to compare several GPS units to each other so that at a glance you can sort them out by which features you really want, which ones would only be nice perks and which ones are definitely yes or no features for you.  Do you want it to be small and thin with a great battery life so you can carry it with you to find your way back to your car? Do you want lifetime traffic?  Bluetooth?  You get the idea.  Anyway, once you have it narrowed down to possibly one or two favorites, it becomes simple to go back to Google or your favorite GPS store and see which one they have to offer, which types of accessories you will need and for what price they are offered.  I just think it totally simplifies your shopping experience.  I like simple.  After all, I would rather be spending time exploring with my GPS unit than sitting in front of a computer trying to figure out all the pros and cons or entrusting my decision to someone who doesn't even know me.  Well, good luck in your search for the best GPS units for your needs and budget, and I hope this helps.
