Cheapest Cisco Router for BGP?

What's the absolute cheapest Cisco solution to handle the whole BGP table? I've been told that BGP is not cpu-intensive, so the main thing you need is RAM. So what's the cheapest Cisco router that can be configured with 2 10/100 interfaces and handled the whole table?

I don't know who told you that but scanning a routing table can be a real cpu hog when you have one or more full feeds.

One whole table or two? Inbound soft reconfiguration?

I don't know if it is the cheapest, but a 1841 with 384 RAM will handle a lot of sessions. The CISCO1841 comes with 2 10/100 interfaces and 128 MB and is $1,395 GPL. You have to add some $$ for a BGP capable version and some other $$ for additional RAM.

I wouldn't even try it on anything less than 3745's loaded up with RAM. BTW, scanning the routing tables can eat up CPUs.
