cisco routers (refurb)
This is the one problem I had with taking the CCNA - no routers to practice on. Since then, I found a website while looking for a retail resale shop for my company's old Cisco switches (trade-in deal only for routers) - www.networkliquidators.com. I'm not sure how it compares to Ebay as I don't trust Ebay one bit, but I found many of the smaller non-enterprise routers to be quite affordable. Many switches and other devices from nearly all manufacturers available.
