Ham radio itself is fun but depending on what you plan to do / learn will determine equipment costs.
I started off just listening in and very rarely transmitting so i had a very cheap setup. PC was my transmitter and had a small antenna plugged in.
Later on i got into pirate radio and intercepting encrypted frequencies. that got pretty fun but quit that shit as soon as i got lazy with encrypting my shit.
all in all. it can be fun but ultimately the internet replaced HAM radio.
