I saw a SNPA clone in the recipe database, here:

But he didn't say how it came out- good, I assume. Maybe you can pm him or he can chime in and say how it turned out.
And this one comes from BYO:

And yet one more:
6.6 lb Light Malt Extract
1.0 lb Crystal Malt (40-60L)
1.0 oz Perle Hops (60 min boil)
1.0oz Cascade Hops (15 min)
1.25oz Cascade Hops (5 min)
1.0 oz Cascade Hops (Optional - Secondary fermenter dry hop)
Wyeast American Ale Yeast 1056
3/4 cup priming suger
Instructions:
Put the 1lb crushed crystal malt in grain bag and steep for 30 minutes in 1.5 to 2 gallons of water. Heat to approximately 170F (not exceeding 180F), remove grain bag, bring water to boil, add extract and boil one hour adding hops at appropriate times.
Ferment in primary one to two weeks. Watch your ferment temperatures, try to keep them in the 63F to 68F range. (Optional) Dry hop in secondary for one to two weeks. Add priming sugar and bottle
So, there are a couple right there.
