You're in a good area to find Hoboken Guilds. I constantly look through Craigslist (some people are addicted to facebook.....I'm addicted to Craigslist) and I see more Guilds in the metro NY area than anywhere else. You will see them all around, though. Just type Guild and check the "in title" box and you'll expand the area being searched.
Also, if you have not already done this, go to the Vintage section of Guitar Center. I've found tons of guitars in there that you can do the generic guitar search and they won't come up.
I expect you'll find something in driving distance if you're willing to drive a couple hundred miles. I am exactly like you in that I want to play a guitar before I buy it.
Happy hunting!
