You should definitely check out Panorama at HPN. Not sure if they have a multi, but I did some complex work there in their 182RG. It's a very nice facility and their planes are very well maintained. I had very good luck with the instructors that I used and got along well with the management there. You just have to know that you will be paying an arm and a leg per hour. I did most of my training in the Midwest, but there is definitely something to be said about training in the busy NY airspace. Good luck with your move out there!
