Mio 330x has been showing up at places like CC and Staples for appx $200.

Also plays MP3's out of the box.

The software is "overlaid" on top of a Windows CE operating system. You can hack the unit, load an SD card with whatever software you want in addition to the GPS mapping program (ie spreadsheet, notepad, calculator, Doom, etc) and you are off to the races. An SD card can also hold additional maps (Canada, Europe etc).

Native maps are 3-4 yrs old but an update should be coming soon. Also, the supplied package might not be the best if you are doing lots of offroad/tertiary road travelling. For the 98% of us that stick to paved roads, the software should be fine.

The GPS comes with a USB cable for connection to your PC/laptop. There should also be a way to download the NMEA string generated by the GPS so that you can use the GPS with your own PC map package (ie Fugawi for offshore and aviation sectionals or one of the MS/DeLorme programs for more detailed mapping)

Got mine last week and I am still on the learning curve. So far, so good.
