I've always wanted a GPS for my bike and have hesitated from buying one for various reasons: cost, complexity, another item to charge, etc. However, this popped up in my radar and I impulsively took the plunge and ordered it. It's a refurbished ASUS R300 GPS that is so small that it will be great mounted to my bike.
It sells/sold for $40 shipped and is the lowest price I've seen for a small GPS unit that's battery powered. Hopefully, it will work well and be useful on my ride!
