What routers do folks use these days?

[Jawaid Desktop <jb () forethought net>]

We're a service provider, and we have a network full of Cat6509's. We 
are finding that we are outgrowing them from the standpoint of their 
ability to handle lots of large routing tables. Obviously their 
switching capability is still superb but one of them with 20 peers is 
starting to groan a bit and RAM is going to be an issue soon.

What do people use these days? Our backbone needs in the next 2-3 years 
are going to be sub-100Gbps.
