Used Reus, in summer of '06.
It's not very busy, very cheap by UK standards, and as Avgas available via fueling truck.
Like most things in Spain, it doesn't move all that quickly and is tied up in paper work. eg. Flight plans must be issued by the flight planning office, as evidence to get back airside...it doesn't matter that you've already filed them yourself.
Fuel took it's time, but came along.
