He is absolutely dreadful to buy for. Works a lot and does long hours so not much hobby time. He like star gazing but has a telescope, makes home brew but has a lot of kit, and likes campervanning. He might potter about cooking but doesnt 'do' gadgets so pretty much everything I thought of has been discounted 
This is made worse by the fact he is 60 3 days after christmas so it's either a small christmas present and a big birthday present or some sort of joint thing.
Any suggestions?!
