Hi Ross.
I was in the same boat as you a few months ago and did look at a few Pipers before deciding on a Cirrus. I have never flown a Cirrus prior to starting my transition training, which is around 10 hours, but I took the opportunity to do a IFR currently as well so it took me longer.
First of all, the Cirrus is very easy to land, especially in crosswind. It is also easy to fly in all aspects but its a little faster than your normal 172.
A few important items to make your purchase successfully.
1: Join COPA, for $65 you get a ton of information and access to very helpful people.
2: get a very detailed pre buy inspection and contract Savvy to manage it for you. (Worth every cent)
3: Get training form a Cirrus instructor. (CSIP). This is very important for your success and safety.
