Tony this is the last pen upgrade with 4,2B system.I pay about 90 dollars.
I agree with you Skude but If I new that this is it I would never buy it.
But there is a second story.When the new one will be up you can't put it in if you not have all the first upgrades.Seems to me that is not OK.
So skude just go back to the 4,1b if you can.You don't miss a thing(For my opinion of course).
