Option Pricing Model

Does anyone have a real world applicable option pricing model that they would like to share?

Pricing options for what?

Like, B-S? http://www.blobek.com/black-scholes.html

Equity options. I have used template option pricing models before but they do not seem to be realistic to real world.

There is a ton of literature available on fixing up B-S option models for stocks. What problem are you having? In particular, are you sure your problem is with the model not with the input volatility?
