If its only VFR flying you intend doing and local bimbling (well sort of !) then the NPPL(M) and a microlight would be the way to go.
I have talked to you many times on our numerous trips across from Ireland to Blighty. I am only a VFR microlight pilot but trips from North West Ireland to all over the UK, right to Lands-End and indeed to Europe is not a problem with proper planning. We have a few trips of over 2000NM done this year already. Microlights can now out-shine much of the heavier stuff in terms of cost/maintenance/performance and to boot it puts grass strips of 200 metres well within its capabilities. In terms of costs they are un-beatable, yes there is downsides to it, but why fly a 4 place aircraft with one passenger !, and weight can be an issue.
Where in Scotland is your nearest airstrip? you would be more than welcome to have a seat on board with one of us guys in one of our weekend danders around Scotland or the UK.
All the best on whatever you decide.
