Best Shopping Cart/Customer Management/Payment Gateway?

[zombies]

Hello,

Any help on the following topic is greatly appreciated.

I have an existing catalog of merchandise. This catalog is updated regularly. Just as well, my product descriptions and prices are all in tact.

What I'm looking for is a SHOPPING CART / CUSTOMER MAGAGER / PAYMENY GATEWAY solution that will support my needs.

What I DO NOT NEED:
- Cataloging
- Product Descriptions
- Prices

WHAT I DO NEED:
- Something to manage customers and orders.
- A shopping cart.
- The ability to post to a payment gateway.

These are the basics. So, anyone have any idea where I should look, or who to ask?

Thanks in advance for all advice and personal experience.

Can't say it is the best but it seems popular and has quite a bit of functions.
