I'm in Germany and the last four times I bought via thinkpad-forum.de. As the name says, it's a board for Thinkpads which includes a marketplace. From my experience, it's considerably cheaper than buying in shops or on Ebay, and the machines are usually described very well. People on the forum are mostly very knowledgeable and include information like battery cycles and stuff like that, so you know very well what you can expect. I would think similar forums exists for other countries as well.
