Would you be happy to fly a C150/2 or a PA28 to do instruction in? Because that's pretty much what a great deal of schools still use.
If you are; then the new breed of Very Light Aircraft are much the same as these, they are just classed as Microlights. I'd be quite happy to instruct on some of these as they are less cramped then the ubquitous C150 and far more sprightly in performance too. However none of the hours you do in these will credit you towards flight experience for an airline - but you don't want to become a jet jockey so it's not an issue for you?
