Im in the exact same boat. Northern NJ here, and ive been up and down craigslist for a month now looking for a 125-150. Ive contacted 2 of the 3 sellers in those craigslist links posted above already, and its too much trouble then its worth.
I also have am afraid that some of these people might clean out the tanks they are selling with bleach or something, and worried it might be a big mistake. But i need something larger for my oscars and RTC
