Do you remember when GPS units were something only the very wealthy could afford? A built-in unit was about $2,000 and a portable unit was about $800. Times have changed quite a bit. Clark recently bought a portable unit for less than $300 and it’s possible to find them for under $200. The more expensive units will tend to have the hard drive built-in to the unit, while the less expensive ones have an SD chip. And there are good and bad factors to both. But they are so simple to use and they have a memory of all of your addresses. These are hot gifts this holiday, so think about one for your loved one. Or wait even longer and they are sure to go down even more.
