For your budget I would go for a low spec (no ABS, no airbag) 300 tdi Discovery automatic with no sunroofs.
Free landers and Discos don't (in my opinion) share many faults. So the engine shouldn't blow up (1.8 petrol), the VCU won't cause gearbox failure and the windows should go up and down for longer.
However, the clutch fork may fail (manual), the cam belt may fail if left too long, the ignition switch and diesel lift pump will need replacing at around 100k miles.
Looking at your location, may I suggest that you join the Solent and district landrover club (SADLRC). I think it's only £20 per year and has plenty of events. We meet on the first Tuesday of every month at the St John Barleycorn at Cadnam so the next meet is in a couple of days, feel free to come along.
