I have a customer that is looking at using BGP for their network; one connection over a few bonded T1s, the other over a Comcast Enterprise connection (which supposedly will do BGP now).
When I was dual homed a few years ago, a 7204VXR with 256MB was more than adequate. With routing tables growing the way they are, what's a good Cisco based solution on the lower end of the price spectrum that should handle this fine for a few years?
Somebody else is suggesting a Vyatta (Linux based) solution, which makes me a little nervous. Then again, Linux has improved dramatically from a security and stability P.O.V, so maybe it's worth a look if there's no hard drive involved.

Any 2800/3800 ISR (except the 2801) will handle this just fine with at
least 512MB RAM if you want to stick with Cisco. You'll get more
performance for the price out of Vyatta if that's more important.

You can squeeze by with 512MB, but 1GB of ram would be better.
A 7204VXR with 1GB of ram will work fine. You can also squeeze by with a 2951
I've been running vyatta, here, for a year now. Its running VPN's and its routing on a TimeWarner Fiber on a modest dual core supermicro server. Its never had to be restarted. Its only dropped its tunnel a few times, but a cronjob checks it and restarts if it goes away.

There was a bit of info missing from the replies in this thread, so I
shall inflict my thoughts onto you all. Sorry, but :

... though you would want an npe-g1 or npe-g2 to avoid frustration.

Any sort of attack traffic will hurt this family in a hosting
environment in my experience. They are good (feature-rich) in the
'branch' environment though.
We are also rolling out huge volumes of Juniper equipment, and medium to
high end J-series equipment is likely to vastly exceed expectations
without exceeding your budget.

I use 2811s in a couple of similar configurations. One of them
currently uses about 400M of the 768M ram with 4 BGP feeds and
"soft-reconfiguration inbound." Another with just one BGP feed and
soft-reconfiguration takes about 300M. Needs a minute or so to recover
from one of the BGP links dropping but otherwise it keeps up with my
light-weight traffic just fine. In both cases the packets are
cpu-switched and normal CPU load (when a link isn't collapsing or
returning) is under 10%.
