Hi, I recently received a Zenpad 8 (model P00A) as a gift. I've been searching for pens only to find out the ones with the features I'm looking for aren't compatible with my tablet. Specifically, I'm looking for a pen with palm rejection and of course pressure sensitivity. I also received an Amazon gift card of $25, so I'd also like for it to be in that price range (but if not, the most I'm willing to spend is $45).
