There are 2 up north. Operate in the Dundee, Perth area. Tayside and the scottish aero club should be able to give you contact details.
And as a personal note try and go to an Ontrack seminar. The one I went to was interesting and informative. The lecture by the Medic was quite amusing and interactive. There are core subjects that they have to cover which will bore the arse off you but they do make it as painless as possible (NPPL and the various forms of gliders with donks comes to mind).
Mates that have been to the AOPA ones didn't seem to have such a painless time.
