I'm assuming that the degradation after 250-300 hosts comes from excessive
arp requests? If not then from where?

It seems like the only drawbacks to using a router or layer 3 switch is
that I loose the ability to broadcast between subnets

It is not a drawback,..it is a benefit.
For Netbios over the subnets you would use WINS,...when WINS is used Netbios
is "directed" instead of "broadcasted" because the Netbios queries are send
directly to the WINS Server listed in the TCP/IP Specs instead of being
"blindly" broadcasted.

and isn't there a performance hit when you go across the router as opposed
to staying local on your subnet?

You are not going to create a "router processing lag" with such a small
network with a single "hop" [router] between the subnets. The benefit of
busting up the Broadcast Domain into smaller pieces creates more performance
then "router lag" would ever take away.

I know Bill said the same thing,..but I just wanted to backup what he said.
