Busters had an offer where they were doing front and rear paddock stands for around £40 + delivery (a fiver I think).
EDIT: Looks like the current offer is this one http://www.busters-accessories.co.uk...paddock+stands
I've got the Halfords mini digital tyre gauge, bought the bigger one to begin with but it was a faff getting it in-between the spokes. The mini one is much better and I keep it in my jacket pocket and use it every week.

I use a track pump from Argos/Evans Cycles to top up air....cheaper in the long run than 50p a week at a garage.
