Alernative to PopUp Domination????

I got popup domination and it only works 1 out of 100 times. Sucks. Are there any good alternatives out there for a exit lightbox popup???? I need it to work with 1shoppincart dot com.

Please PM me if you know of a good product!!!!

You can use default Aweber popup for showing it after X seconds. Or get someone to code it, it shouldn't be expensive.
