Here is probably the most for your money, unless you really want an "economy" one.
$110, minoura with heavy stand, with spring-loaded arms, includes T-bracket for calibration to zero-dish. I really don't know why they are $100+. lol. A motorcycle truing stand is half that.
Mine looks like this and was $40 years ago.

Yes, a common joke, but (re-) installing spoke nipples is a frustrating task without one. Actually, you can insert the spoke nipples without one (I prefer toothpicks), but the first few turns to start the wheel are much easier with a screwdriver.
Some wheels (rare) do not have accessible spoke nipples, and require a driver for all truing work.
