Styluses for x1 tablet

[Crazycow]

I want to buy a pen for my x1 tablet gen3...

internet provided me with these

Lenovo ThinkPad Pen Pro 4X80H34887
Lenovo Active Pen 2 GX80N07824
Lenovo Active pen (NA) GX80K32882
Lenovo Pen Pro-ROW 4X80R02889

but I couldn't find anything that actually explains the differences between e.g. the pen pro and the active pen 2?
Which one should I get?

Get a Wacom Bamboo Ink Smart Stylus 2nd generation. You can find them on ebay open box for cheap, you can get alternate nibs for them, and they work great on the X1 tablet gen 3 (and other recent thinkpads).
