Entry level ThinkPads aren't really ThinkPads, the E-series in particular. Those ones were previously known as ThinkPad Edge, which were designed by a different team.
Sometimes you can find a random business-line HP or Dell with one, but the Dell one I tried (some 7th generation Core i5 I rode for five years at work) was so terrible, especially on scrolling, that I just plugged in an external mouse, and it's a feature that appears on random models intermittently when it does appear, so it might not meet any of my other (admittedly limited) requirements.
