Best router to pair with LinkSys SRW2048?

I've been tasked to look for a router so we can pull that function off of our server and pair it correctly with the switch we already own for our move to a new building.  We have a single 48-port LinkSys SRW2048, a pair of NetGear GS108s, a NetGear FS108, and a Cisco RV042.  I'm honestly not sure why we have those last four items, as the LinkSys isn't anywhere close to full, but they'll essentially be non-players in the new building anyway.)  So what I need to find is a good router that will pair well with the LinkSys to support about 50 hosts (At the most, but even allowing for some possible expansion the building is only wired with 72 ports.)  Does anyone have a suggestion?
