Henry C - The public displays so far have included a lot of short/rolling vertical landings, because nobody wants to resurface the runway after the show. VLs so far have been confined to steel ship decks, AM-2 pads over concrete, and special VL pads made out of the kind of stuff you use to make pizza ovens.
F-35B acquisition costs can be found in US DoD budget:

Operating costs as estimated in the US don't apply to the UK, because the Marines expect to use STOVL on only 10 per cent of sorties. The F-35A is estimated as 27 per cent more costly per flight hour than the heavily used and elderly F-16 force, and the B will be substantially higher because of the cycling of the lift fan and drive mechanism twice per STOVL mission.
