In the US, Thanksgiving heralds the launch of the Christmas shopping season - and an interesting survey in PCMag.com shows that a GPS can now be bought for as little as $80 (£52 or €62).

Author Craig Ellison has been monitoring GPS prices and has found some great bargains.  But he asks just how good are devices below $100?  And, if you're willing to pay a little more, how much better can you do for, say, an extra $50 or $100?

The cheapest GPS appears to be a Nextar 3.5-inch X3 model - it includes maps of the US and Canada but lacks text-to-speech.

Pay $10 more and you can have 1.6 million points-of-interest too.  And for $100 total you can find text-to-speech thrown in as well - the device will talk to you . .

The article goes on to look at devices costing twice as much.  It's interesting reading - but don't rely on these prices translating direct to pounds or euros . .
