i have checked lots of refurb and used laptop, specifically latitude and thinkpad--- please ask for unrapaired item, as most refut company or seller swap original scrren and parts with cheap quality TN screen and low quality keyboard or parts
at times you dont get the feel of using Thinkpad or lattitude and kills whole purpose of it
if speding 30k better go with new laptop, you get company wattanty and original factory condition
i had bought a dell lattidue refurbr, but it was repaired item, 3.5 jack not working, speaker not working
later bought Thinkpad, --only the motherboard was thinkpad, body, keyborad, screen, etc was changed, it did not feel like using thinkpad
later returned it and got refund, just sharing my experience
