that is a good idea.

Paypal is the payment processor that is used widely because of the security of transactions.

I have exercised some shopping carts too. I applied PayPal, this was the customers request, but today I am attempting to built one with both PayPal and Worldpay.

I use the one and only IzzoNet shopping cart, its rather new but i find it to deliver where others have failed. I did encounter chargebacks but it was under 0.5% so it was ok to continue working, but yeah, did have some fone calls and was a bit of a mess.
