Prebuy and annual in the Northeast?
 

The closest place I've seen mentioned on this board is Brooks field in southern Michigan. Anyone know of anything closer?

Thought I'd contribute to posterity here and mention that Business Aircraft Center out of KDXR currently maintains a P model, and previously, an N/A. I talked to them about my hopeless search for the right model and they seemed rather knowledgeable.
