Secondary math is a pretty broad subject for something as individualized as manipulatives, but this is a list of things I'd love to have if I were teaching every subject in the same year for some reason. A two-pan balance scale and a bunch of clearly-labeled weights (Algebra I) - I feel that it can be really evocative how an equation like $3x+4=16$ can lead ...

I might think about some iconic objects of the past that excite interest, perhaps mainly in geometry. Drafting table (probably $500 for a professional one, but you can check second hand). French curve as Rust mentioned. Slide rules. Parallel rulers and 10 point dividers (good for poking people when bored...I would know). Sextant. Abacus. Towers of ...

As a no-cost option that gives you so many capabilities besides the conventional black/white-board, I always use geogebra. Not only as a demonstration tool, but also as a functionality for the students to investigate almost anything in precalculus or algebra. By simply adding, e.g. some moving graphics you can easily explain why, say, $e^x\approx\left(1+\...

I don't know if this is the right dollar amount, but I think getting access to a 3d printer and making some useful manipulatives of your choice with it would be cool. That is, if you are in a large district and have enough time to invest in trying them out - I don't think it's a one-off process! As an example, Henry Segerman's website has some absolutely ...
