I have several Lenovo X220s running FreeBSD and am very happy with them. Inexpensive, good keyboard, sufficiently fast, good battery life, good expandability and availability of replacement parts.
Anything thinkpad really. No nonsense and a sturdy build.
Thanks - I found a very reasonably priced X240 on ebay, let's see how well that works out for me.
