The Sure was considerably easier to use, for me.  It comes with a USB 
lead, so that's the +5V power done, and a serial connector right on the 
board.  As accurate as any of the PCs I have.  It includes the GPS puck 
antenna as well.  Not bad for US $34 (about one third of the price of the 
Garmin GPS 18x LVC in the UK.

We are spoilt for choice!
