Woot has listed Linksys E8450 for $19.99, and a Linksys E9450 (what is this?) for $22.99.
Available for the next 7 days as of this post.
Both are categorized as "Factory Reconditioned" and have a "90-day Linksys Refurbished Warranty."
I bought a previously listed "Refurbished" version in February; see unboxing photos here.
