Want to Acquire Thinkpad T400s

Hello, I'm currently using a librebooted x200, and I want to upgrade to a t400s (for the screen, increased CPU cache, and touchpad). However I can't seem to find one anywhere. I was wondering if there's a cabal of thinkpad enthusiasts who could help me look somewhere better than ebay. I already own a t400, but it's honestly too bulky to fit properly in my backpack with the rest of my belongings.
