Re: Plenty of X220s on eBay
actually, a reasonably well-kept 2nd hand x220 would cost quite a lot more - if you want a better processor (i7), screen (I forgot what it is), usb3 support, ssd + extra ram, altogether around £400, I'm afraid.
p.s. but still, SO MUCH BETTER than my wife's dell-whatever-the-flagship-equivalent costing well over a grand. And this is 2011 v. 2017 machine...
