I'm in the market for a good stylus as well(gonna try to do more concepts on my phone). I just ordered 3 pens for $2.20 from Amazon. They're gonna be cheap, but I just want to test it out before I get an expensive one.
Also, just saw this while browsing the Jot site, http://adonit.net/product/jot-touch/
"Not all lines are created equally. Jot Touch reacts to the amount of pressure you apply to deliver more accurate interpretations of your stroke"
My only concern is, the pressure sensitivity is only relative to the app you're using, as far as I know. The only good Android app is Autodesk Sketchbook Mobile, which doesn't support pressure sensitivity I don't think.
