You need to talk to a chap at Enstone last I heard. I think the name is Steve McCurdie or similar. If someone knows better, please post a correction. He used to, and may still, run a business finishing Europas and the like with a sideline speciality of refurbing Quickies. He is the guy who owns/owned the only Rutan Defiant on the UK Register. He has more time than anyone else on the type.
Check the hours flown on all the examples you come across. Few seem to exceed 100.
BEagle has flown one.
