I don't currently live in Kingston, but I used to. I try to get up to the KARC fleamarket there each November. Maybe I'll see you at one.
As previously stated, KPD are now encrypted and unmonitorable, but with a digital P-25 scanner, everything else you want to listen to should be possible. Not sure if Correctional Services are encrypted. I'll let someone else local answer that one.
I really like my Radio Shack PRO-106 handheld digital scanner. It works great on Fleetnet, especially the "Roam" mode which automatically selects the best tower (assuming you have them all programmed for Zone 2 of course.)
Why not take a drive to Watertown NY? There are two Radio Shack stores there, one at the Salmon Run Mall and the other on Arsenal St. (Route 3) just East of Interstate 81. There is also a store near Fort Drum, about the same distance, but there is more to do in Watertown. See:

Or wait for a sale, order on line, and go pick it up at the Wellesley Island "Ship To The Border" location.

This will work for any supplier, by the way, not just Radio Shack. I often use a similar service in Massena NY, which I am not too far away from. Declare it at the border, go in and pay the 13% HST, and you're done!
