Router shopping

[Yuka]

With the introduction of rapidly increasing available bandwidth to myself... I've realized that my current router (Netgear FVS114) is not keeping up. The router itself is unstable at high speeds, and caps off with an 11.5 mbps total throughput of the WAN-to-LAN interface. Essentially, it has become my bottleneck, considering my allotted bandwidth for my WAN connection is nearing 30 mbps.

I'm looking for a new router that will carry me on into the future.

As far as operations at my residence, I perform more than the average user, gamer, or power user even. I have a rack of servers that host all sorts of services, from HTTP, FTP, mail relay, dedicated game servers, ventrilo AND teamspeak, and a slew of other services that tickle my fancy. Most of these services are web-accessable, meaning they will have to traverse the WAN-to-LAN interface, essentially the routing interface, of any router that is in place. This means I need a versatile router that can stand up to the "punishment" that my network will give it.

I have only worked on Cisco routers in an educational lab in a single semester crash course in CCNA. That was nearly 5 years ago. I haven't worked on cisco routers, or anything besides my own, since. I haven't retained much of the proprietary knowledge, but I have retained the concepts and foundations of routing.

I'm looking into the Cisco 2600 series of routers but I'm having a hard time finding out what module I should buy to connect to my WAN link. Obviously which one I need to purchase is based off of my WAN connection, which in this situation is currently cable internet, but I imagine the delivery to my WAN interface will not change, so we'll assume I have an ethernet connection to the web that dishes out an IP address via DHCP. (Stand-alone cable modem with ethernet interface in this case.) I'm thinking I'll need an ethernet module.

My criteria for the router:
- Have a WAN-to-LAN throughput of greater than 60 mbps (I think it's called the routing interface... it's been a while!)
- Accepts modules for various interfaces
- Have at least one 10/100 mbps RJ-45 LAN link built in
- Accepts more than one module (example: I could have two WAN cards to accept two different WAN links)
- Configurability level that rivals Cisco's level
- 1U Rackmount
- ~120 VAC power input
- Total cost, including modules be less than $200 US. (I'm on a budget, shucks!) That considered, I would consider a used router from a trusted reseller.

So, would your suggestion be to get a 2600 series cisco router or something else? If I go with the 2600 series, should I just get an ethernet module and call it a day?
