Rmarvin86:
Old Sarum is about 35km North of Bournemouth and now has three PA28s (glass cockpit and conventional), two AT-3s and a Bulldog - more aircraft will probably be arriving over the next few months. There are also flexwings, C42s, Sky Arrows and Shadows available. There's even at least one Italian at the airfield.
For hours building the AT-3s would give the cheapest option but they're VFR-only.
