Anyone know of a cheap gps tracking system for a car?

Being a Truck driver and driven 48 states, I bought the Garmin. I bought mine at Cosco. Using the Internet and bought mine on line which saved me about 100.00 dollars, and received it in 3 days.
I am very happy with mine and have not had that much trouble with it. And the screen is a good size, I bought the 200w, and paid less then 200.00 dollars at the time, now they are a little cheaper now, since I bought mine about 3 months ago. There are cheaper ones out there, but have not the features and easy use. Sending the link and hope you check it out. Good Luck
