Looking for suggestions for a device (switch/router) that can speak BGP

I know a 3560 switch can do BGP and wouldn't have the throughput
limitations the router lines have. The cost is probably going to creep
up again though when adding Enterprise code for BGP support.
ASR920 or so... throughput will be fine, price of 2000$ "should" be
achievable (depending on interface and license options).
The caveat, of course, is that it will do exactly 20k prefixe, no more
- so if you might go "up to 30k", it's not the platform
Or a used 7201 / 7200/NPE-G2... dirt cheap, 500k+ prefixes, but not much
more than 500Mbit/s throughput.
Your triangle of "number of prefixes / price / throughput" is hitting a
somewhat weak spot in Cisco's portfolio...

Thanks for the response, Gert. It looks like the 920 would work but I'm
seeing that it is already End-of-Life. I'm having trouble finding what
Cisco recommends as a replacement for it. Anybody have an idea?
Thanks,
