Aside from Paypal what is everyones choice gateway and module for their site? I am looking to get away from paypal because of some limitations they have.

On my site I sell video games, and a majority of my sales come from people being able to Pre-Order them. The problem I have with Paypal is they only allow you to capture funds on an authorization for 29 days and no later. People could preorder a game 6 months in advance and I have no way to charge their card at the time of shipment.

Does anyone here know a way around this problem or recommend a service that would allow this that works with Zen Cart
