I'm a cheapskate who likes expensive stuff. Fortunately I'm also a patient cheapskate who waits until prices come down. The months after Christmas, when all the Christmas goodies get returned to the manufacturer and excess inventory is sold off, are great time to bargain shop for "refurbished" goodies at half price or less.
Right now Buy.com (and several other online retailers) have the $300+ Garmin StreetPilot C320 on sale for $130.00 after a $20 rebate coupon. The C320 is an everything-you-need, nothing-you-don't GPS that guides you from wherever you are to wherever you want to go, has a built-in basemap of North America that includes a database of gas stations, parks, restaurants, etc, and allows you to enter hundreds of your own destinations to the database. It's very easy to use.
When driving it verbally tells you what side of the street/freeway you need to be on for your next turn, how far that turn is from your current location, and recalculates a new route to your destination when you miss a turn. You can also program in a side-trip to an attraction or have it guide you to a gas station while en-route.
Things it does not do: It does not call out street names or allow you to plan out a trip wth multiple stops along the way. (Something fancier units do.) It does not play MPEG music files or hook up to a backup camera or do anything else that isn't GPS/Navigation specific. It can be moved from car to car, runs off a cigarette lighter adapter and has its own 6-hour battery
, but it is too bulky and lacks the features needed to be used as a hiking GPS. It's not waterproof, either, so no good for a motorcycle.
In other words, it's a useful tool for a cheapskate with a poor sense of direction hauling a trailer around.
