Routers supporting PPPoE + IPIP tunnel

Because of the recent shipment problem of Cisco, I am looking seriously for a cisco 827 substitution. What I need is a router which support PPPoE + IPIP tunnel with Ethernet (or DMT) WAN port. Do you have any idea for products other than cisco which support ipip tunnel? I've tried Netopia, however, it doesn't support ipip tunnel. Many thanks! Cho
