Best value-for-money in terms of cost vs airport busyness, IMO, is Manchester. It's not cheap at around £50 off-peak for a C172, but considering how busy it is, it's a far better experience than Bournemouth for someone looking for a "big airport" experience for about the same price.
BTW, the BIGGEST thank you must go to FARNBOROUGH who are also very busy these days and yet can still find time to accommodate an approach with relaxed humour and attention, even if they're shattered
Do Farnborough still allow you to turn up un-announced for an ILS, and let you down to minima without charging a penny?
