There is a great deal on the SporTrak Pro at Costco (if you have them in your area). The package includes the SporTrak pro, power cable, PC cable, clip case (like a cell phone case), automotive holder, and the MapSend software. $289 with a $50 rebate.
I noticed there is a different package on their web site at www.costco.com. Missing the auto adapter but includes a canvas case vice the cell style case.
I'm very happy with the package deal.
