The Arrow is a nice aeroplane. Flies a bit like most other PA28's only it's a bit heavier on the elevator and obviously flies a little bit faster.
There will be people on here better qualified than me to advise you about which variant of Arrow to go for, but I thought I'd mention something about turbo charged aircraft.
Having a turbo charger on your aeroplane will add quite a bit to your maintenance costs and unless you're going hot or high, you will see relatively little benefit from it.
In this country, for most people, there will be little benefit to having a turbo charged aeroplane unless they are instrument rated and can get up into the airways (or regularly go somewhere with density altitude issues etc.)
As you probably already know, retractable gear will also add quite a bit to the cost of maintenance so unless you have reasonably deep pockets, you might be better off looking at something like a Cessna 182 which has fixed gear but still has plenty of grunt.
