don't overlook the 206 JR or LR. As with any helicopter there are pros and cons.
In rough weather, if you have the brains to slow down then they will handle the weather almost as well as a 500 or 350, and if you are flying for pleasure you should just be able to look out at the weather and say, oh well we aren't going today.... no point taking your family out in conditions that could kill you, no matter what helicopter you are in!!
They are slightly slower than a 500, but give you more room for the money. A JR should be about 1/2 the price of a 500 and a good LR about the same price, as a 500, and a LR is way bigger than a 500 and is quicker than a JR.
You also get a boot in both of them, and you get a far greater range than you will from a 500.
Way easier to put in a shed, only need a single 3 m wide bay to slide it in.
A good bell engineer will get them to track as smooth as any other machine, or if you are real clever like Dick Smith you put the magic balancing machine in the nose and they will then be silky smooth
make sure you look at real Bells, not Agusta Bell, otherwise it gets too hard.
