Hey Steve (or anyone else), How much RAM are you running on your 4431? We have a similar application and are trying to figure out whether to order a 4431 with the default 4GB RAM, or upgrade it proactively to 8GB to support the full BGP table.

More current model would be the Cisco 4300 - 4400 ISR series. They have 2/4/8/16 gigs of memory. Power consumption MAX ranges from 0.6A to 3.0A depending on model. Higher models have more throughput and more interfaces. Throughput ranges from 35 mbps to 2 gbps. I rarely see Cisco routers running near the max power rating especially if you are not using PoE or etherswitch interfaces. The 43xx series is replacing the 29xx series and the 44xx series is replacing the 39xx series. I've put in a few of them and they are pretty nice. They are either 1 or 2 U in size. We are using 4431 with throughput license to 1 GB receiving a full table from the provider and three IBGP peers with no issues and full gig throughput. It is currently drawing 65 watts of power in steady state and 250 watts on bootup (not using any PoE or network modules, just built in Ethernets).
