Depending on the router, there are alternatives to Merlin, such as DD-WRT, FreshTomato, OpenWRT. Heck, these projects are *still* supporting the original Linksys WRT54G! So there's no need to throw them away or sell them. You could even reconfigure them as simple APs, a wireless ethernet bridge, guest network, VPN server, SSH server, etc. Lots of useful life left in these devices beyond just ASUS OEM or Merlin firmware.
