Payment gateway query

[Luki]

Hi Guys ,

Does anyone know some open source or free payment gateways , if not free than very cheap one?
Basically have online gallery web - project, where you can buy now , or negotiate and then buy a product.
Once it goes to 'buy now' then the payment should be processed.

PayPal is not suitable for auction (many sellers to many buyers). Any other ideas?

Thank you,
