Ghengis is your man on this, but i believe there are only 2 places in the UK currently that rent microlight. One in n yorkshire and the other in wiltshire. Unless you are near one of them, youll need to buy outright, or into a syndicate.
Also just worth following up,as 2k is very cheap for the course. I dug into this quite a lot, and couldnt find anywhere even close to that, though i am down south!.
Good luck, IPZ
