What stylus is the best for drawing on iPod touch 5?

I'm about to get a new iPod touch gen.5, and I'm intrested in drawing with it, for example with ArtRage.

I would like to know what stylus is the best for drawing?
I found Pogo Connect (http://tenonedesign.com/checkout.php?product=Pogo%20Sketch%20Pro), but I don't know if it can be used with iPod?

Thank you in advance!
