If you can afford it, using 2 type 2 4-port GigE PICs will give more spare capacity than using 1 type 3 8-port PIC - the type 2 FPCs on the M120 can take 4 PICs, while the type 3 FPCs can only take a single PIC. That means that using 2 x CFPCs, 2 x Type3 10GigE and 1 x Type3 8xGigE, you've filled 5/6ths of the FPC slots, and filled the FPCs in them to capacity. If you use type2 GigE PICs, you've still filled 5/6ths of the FPC slots, but one of your FPCs is still half empty.
The second option is the EX platform, if you make 2 EX 4200-24s into a virtual chassis, and put the 2x10GigE uplink module into each one, you can create a router / switch with 48 GigE ports and 4 10GigE ports. This will be the cheapest option, but the code is still maturing, and I'm not sure its capable of handling a full BGP table (I think theres a sub-100,000 route limit). The final, and probably best option, is the MX series. I don't have any direct experience with this platform (yet), but you could use an MX240 with a 10GigE and a GigE DPC-R which would meet your needs. As others have said, and as with the EX option, you will have rather more GigE ports than you wanted - 40 instead of 8.
