FWIW, I ended up going with a Viair 400P that I got on Amazon for $179. It fills my 35's from 10psi-24psi in about 2 min 15 sec. It comes with a nice bag so it is secure and put away. I don't have to fill up CO2 tanks. It's always ready to go and I can transport it to other vehicles if I am going to be on the road without the Jeep. All around win for me. Thanks for all the ideas. I'm sure they will help others make a decision as they helped me.
