Buy Physics Classroom Demo Equipment: Quality & Cost Guide

[whoohm]

What are the best options for buying physics classroom demonstration equipment (e.g., air track, optics, etc.)? There seems to be several options/sellers out there, but it also looks like the quality of equipment varies. It is hard to tell from the online photos and descriptions what sources are best for quality demonstrations and long term use. Any suggestions? I will be donating some equipment to a local school. Thanks.

Have you asked the instructor(s) what their needs are and if they have any preferences or recommendations?

Yes. I am doing that. And that will get priority. However, I am also curious to learn from a wider audience about these questions. Call me curious to read from more than one source. ;)

What's the course's syllabus? Elementary mechanics? Optics?

High School Physics and AP Physics. Specific needs in E&M demos/experiments.
