I've not had any first hand experiences with the Centri.. But I've heard both sides of the story so far..
I think it's a lot easier to support builders in the USA if you are based there too. But for us guys across the pond it really can be much more of a pain in the proverbial if you have any problems, for all the obvious reasons.
I wish Mike all the best and really hope this version of the Centri is a flying success right from the off... Then I guess we'll kicking ourselves if we haven't jumped on his offer..
