But yea, it's cheaper if you only count the material cost and if you only go for GPS and accelerometer.
Why don't you bring your phone when running tho? There are armstraps for most smartphones that makes you almost forget that you even have it with you.
I for one would never leave my home without my phone, it's just unimaginable.
