The OP said he wants physical, and I understand. For fiction or news, I am fine with my Kindle, but for tech manuals where I want to rapidly bookmark, highlight and reference, paper is really handy.
Ever since I got an iPad Pro 12", my requirement for physical copies of technical books has gone down a bit. Often times it's the more convenient option.
I read technical information slower and in shorter blocks of time, so being easy on the eyes like my Kindle isn't a requirement.
