Any good Wave Boxes to do this?

I have seen boxes from MRV and others that will do 2GE into an OC48. I really feel bad about "wasting" that 500mb/s on essentially an IP application, but can't really justify putting OC48 ports into a catalyst 6500 of this application. Likewise, uplinking to a GSR just to get cheaper OC48 ports doesn't make sense when you count the cost of the GE ports. Is there a good box out there that will say take 2xOC48 and give me 5 GEs?
