I don't own this one, but
Amazon reviews suggest it's pretty good. It's probably a bit on the inexpensive side of your required price scale (considering I work on military grade components and know how expensive such trivial items can cost). It fits your other requirements, but unfortunately you didn't mention what the full-scale accuracy needs to be. It reads to 0.1 psi resolution, but with a full-scale accuracy of 0.5% which apparently is good enough to be considered "professional racing accuracy standards."
From a quick search I didn't find anything that provided a lower full scale AND also listed the full scale accuracy.
FWIW, finding out the recommended distance to plant geraniums from one another is much easier to find.
