Expensive in terms of people, perhaps, in that it doesn't run out of
the box.  But once the config is made, it is fairly easy to maintain
and has some nice properties that you can't easily find on vendor
routers.  They also tend to have bigger queues than vendor routers.
On the downside, the newest generation of routers blows the doors off
of the workstations, especially in terms of packets per second.  (For
example, the last years Alphas push something in the 3000-5000 pps
range, where the vendor routers go 20-100 kpps.  Don't know what this
year's model does.  Note that 3000 pps is full FDDI if people use
reasonable -- 4kB -- packet sizes, though).

The real rebuttal I wanted to make, though, is that the Alpha
workstation costs in the $10K price range, with about $1200 per
interface for FDDI (less if you can do the UTP business which alas we
cannot).  Compare this with todays prices on vendor routers and then
tell me if you think it is expensive...

I should add that we haven't extensively tested the CIDR stuff on our
Alphas since we don't currently take full routing tables.  But if
Curtis says it should work I believe him :-)
