A new cisco 2851 can be found for under $10k and can take a gig of
RAM. If your goal is to have fine-grained routing data, and not to
carry gigs of traffic, that particular router is perfectly adequate.
If you're prepared to consider second-hand equipment (which seems
fair, since it's not as though the real Internet has no eBay VXRs in
it) you could get better performance, or lower cost, depending on
which way you wanted to turn the dial.
Sometimes it's important to appreciate that the network edge is bigger
than the network core. Just because this kind of equipment wouldn't
come close to cutting it in a carrier network doesn't mean that they
aren't perfectly appropriate for a large proportion of deployed
routers which take a full table.
