It would seem to me that much depends on whether the original poster wants to end up with legal logbook entries.
If so, he will have to hire/borrow/buy a plane or a part of and fly it.
If not i.e. if he just wants to stay current, there should be a fair number of pilots, some with very nice very expensive planes too, who fly regularly and who would happily take somebody up who, in return for being allowed to fly, will give them a little wad of cash at the end
