best router for apartment complex

I'm looking to get a new router for my apartment complex. At peak
operation, I'd be servicing no more than 48 network devices in 16
apartment units, mostly desktops and laptops used by the renters with
the exception of one web/email server visible to the outside. I'm trying
to find an effective solution for as little $$$ as possible, preferably
something under $200.

In order of necessity, this is a list of features for my ideal router:

* NAT

* a good track record for remote operation such that I won't find myself
having to make an inconvenient trip to the complex to punch a stupid
when a packet gets jammed somewhere. This is what is happening with my
BEFW11s4 which is currently handling the routing for this place.

* a good firewall. I don't know much about what makes a good firewall,
so I'm open to recommendations on what would be good here.

* 10 MBPS. That's all I really need for distributing broadband. Faster
is okay, but this is all I really need.

* SNMP management and monitoring

* web-based management (though ssh or telnet would suffice)

* dual WAN connections in case one goes out.

* compatible with the Cisco IOS features of my Catalyst 1924 switch

* some way to logically separate units of the apartments complex for
security and bandwidth management. VLANS? My CAT switch can do
port-based VLANS, but requires VTP functionality in the router.

* dynamic domain name service client, similar to the one found in most
netgear home routers

* integrated or modular support for an ADSL bridge.



I'm leaning towards getting a Linksys WRT54G ($56 at NewEgg) and putting
some 3rd party firmware on it, but I have reservations with Linksys
equipment after my experiences with my current router.

so... any recommendations on what I should get?

Thanks!
