I have a gym and have for a long time. Our speed bag platforms have seen their better days and need to be replaced.

The last time I went looking for platforms, I didn't even have Internet. I don't think it even existed back then. I'm a bit lost in this. Anyway, I'm looking for speed bag platforms that are of exceptional quality. None of that particle board crap. I want a solid platform with no rattle. Professional grade.

Can anyone point me in the right direction? C'mon, it's for the kids! I want top-level platforms, but I don't wanna play $800 for what I coulda gotten for $400. What are the gems out there?

Thanks and sorry if this is clogging up the board, which I know is more for boxing chat rather than my individual cockamamie concerns. Thank you.
