How to get started with music production

I’ve been getting into music production allot lately, with FL studio and a super old Yamaha keyboard from the 90s. I wanted to get into more modern equipment like MIDI keyboards, electronic drums, and learn how to make music Synthesizers. So it occured to me that some people on the forum probably have some experience in this field. What equipment do you guys think I should buy within the price range of 250$ to get me started in making music?

Thanks in advance.
