I'd like to select a Gateway Intermediary that supports Automatic Recurring Billing for Credit Cards. This is to support installment payments (e.g. 4 easy payments of $29.99), but I've noticed that most open source shopping cart solutions don't support it, and support form gateways like Authorize.net is spotty.

Does anyone have any experience with this? I'd be most appreciative for any suggestions.

Thanks

Tom
