There's been a lot of talk so far about what type of a/c to buy (into) but I always at this point bang on about the other members of the group.
I beleive that the make up of the syndicate or group is as if not more important than the machine.
Try and find a group of like minded people. Don't just buy something cos you fancy flying it only to discover one of the members is an hours builder and flys the pants off it. Or is dodgy at landing and is collecting insurance claim forms. Or is a compleat self abuser.
Ask around at clubs etc. You'll soon hear which groups are envyied for their camaraderie and eficiency and which are to be avoided.
Finally once you find this ideal group dont tell everyone just PM me there's a good chap
