My 2 cents worth.
I've been looking around coming to grips with what fixed wing aircraft I would like to own. I've only flown in a few Tecnams, Savannagh's but all powered by Rotax (also my own 503). I like the look of the Jab's and Aussie and better Qld product BUT I look at the For Sale adds and many have different hours Engine to airframe etc and not big airframe hours, new heads etc. This is even aparent on the Jab site.
From reading this thread I can see many people love their Jabs and a lot are very hands on mechanically and maybe thats what Jabs need. For me, I don't want to increase risks of engine out unnecessarily especially as my kids are most likely my passengers.
I wont buy an aircraft powered by a Jab motor, I understand the process of time and use to make them better and i'm sure they are a lot more reliable now than previous BUT for me i'll go Rotax. Pity Jab don't have a rotax option.
