Go on
www.tirerack.com and punch in your size and a speed rating of at least 120. This is what I did when I needed some tires. Can't see spending the money on "purpose built" skinnies if there is such a thing.
EDIT:
I jst checked for you and there are a bunch for under $75. Just make sure to geta 65 - 70 series rires for extra roll out and so it does not look like you are rollin' on blades.
