I'm sure there will be lots of responses but here is my twopennorth.
Firstly, identify what you want to do with your license. If it is to bang a PA-28 to the gills with four people and go fly then you will not be going too far. If however there will be you and one other then look at a syndicate around a Eurostar or similar Rotax powered machine. Often classed as microlights they are in effect a vastly more efficient C150 or PA-38. Average costs run around £3k for a share, £60ish a month contribution and around £30/35ph wet.
TT in adverts means 'total time', TBO = Time Between Overhauls, TSO = Time since overhaul and lots more. If you are flying purely for fun then I would err towards a permit to fly aeroplane rather than a full EASA type, lots about and generally vastly more fun than standard trainers, and a lot cheaper in the long run.
Before you make a choice go and try a few out. Many schools have a different type of permit aeroplane so go fill your boots then choose what is right for you.
