I referenced this router back in
May of 2010 in this post. It is again on sale at Newegg.com for $49.99 with Free Shipping. If you are looking for an inexpensive replacement or a backup in case yours takes a shit on you, I'd highly suggest picking this up. There are lots of shitty commodity routers out there but this is one that is actually solid and a proven performer. If you have router issues this might be one to think about.
Here's the link. Sale ends President's Day so you have 4 days to pick one up.
