I'll start with one that I know well, as I've been using it for over a year. CommerceGate.com I've used them for an adult business so for anyone out there interested, they accept those (although with a commission way higher than usual). They let you use your own template/design for the order page, take international orders (of course) and overall I have no complains about them.
