I have not used the asr1000 but it looks like a capable box. You would do well to look at the MX80 fixed chassis, it comes with 48 1G interfaces and 4 10G interfaces. They are pretty good value, I think.
The thing the MX80 has that the ASR1000 is port density. You get lots of Gig-E ports in there and a couple of 10Gbps ports too. Not too bad. The ASR1000 has an 8-port Gig-E card (called a SPA - Shared Port Adapter) that offers the most dense Gig-E port capacity in a single-height line card. There is a 10-port Gig-E SPA, but that is a double-height unit, i.e., it eats up 2x slots. 10Gbps port density on the ASR1000 sucks a bit; there is only a 1-port SPA, and no built-in 10Gbps ports unlike the MX80. But on the other hand, the ASR1000 is great if you're looking to throw in some non-Ethernet SPA's, e.g., serial, E1, T1, SONET, SDH, e.t.c. The MX80 won't do this efficiently today, and is really best deployed in Ethernet scenarios. Also, the MX80 can come with rather complicated licensing structures even for the ports you want enabled, if you want to take advantage of their cheaper offers. This can get hairy. Mark.
