Boxing Gyms NY?

Does anyone know of boxing gyms in Manhattan? I know there are places like Gleason's down in Brooklyn and I have heard there's a Police Athletic League gym in Harlem somewhere that could be usable.

I'm mainly just looking for a ring I could use with a friend. Down the line I may be looking to actually train, but I'm not sure about that since I have 3 fractures in my back. So if anyone knows of a place I'd be able to use a ring to spar without the cost being off the wall, I'd appreciate the info.

Kingsway Boxing is on 28th and 5th. It's run by Michael Olajide. check it out...come train with the best coach around :) yours truely
