For a good D.T.M.F. telephone try an "Western Electric" 2500.

The touch tone exchanges always supported BOTH the touch tone and the old pulse dial phones...Many of those exchanges also supported disabling the touchtone dialing recognition...That way they could make touchtone an optional extra cost feature of any line... (by that time phones were no longer provided solely by the phone company so you could go to an electronics store and buy what ever phone you wanted).
Also, not all pulse dial phones here in the states were rotary...I've seen many early pushbutton dial phones that had a "pulse-tone" switch to select which way it would signal the exchange with the dialed number. IIRC there were even pulse only push-button phones available for a while.
