I bought my SMC7004AWBR for $150, but I have seen it for $99 after reabtes before.

Do yourself a favor and buy a brand name router. The firmware on these types of things is updated regularly for security and added features. I have an Addtron USB client that is pretty-much worthless because Addtron hosts their drivers and firmware off a free dyndns.org domain. Any company that would do something like that, and then not update the entry is bad news.
