Getting hold of older-style promethean pens?
There have been noises from resellers that it's getting harder to get packs of replacement pens for promethean boards, particularly the dark grey pens with the orange band. Trying to get hold of a ten-pack is proving difficult.
For how long do Promethean guarantee a supply of / produce replacement pens for a given board type? Does a 3rd party make compatible pens if a pen+board type goes end-of-life?
Since the boards are rather indestructable (with little functional difference between versons - and IWB is an IWB), we only replace them when they suffer catastrophic hardware failure.
