I'm in Chicago. I've had the mic for about 6 or 7 years, bought at Guitar Center. It has not seen heavy use, as I don't do as much recording as I anticipated when I got it. I'm selling it because I have an AKG 414, which as you probably know is multi-pattern, so it covers more territory.
As for guarantees, I'm not sure what type of protection Paypal has for the buyer (if you use Paypal.) I think there is some. I'm not sure what type I can offer other than to say, if you have problems with the mic (you won't), you can send it to me and I'll refund your money.
