If you are interested in pipe organs but can't afford one, check out Hauptwerk and its collection of hundreds of pipe organ sample sets from everywhere in the world.
Check also its open-source alternative, GrandOrgue.
Musicians spend thousands of dollars to build MIDI organ consoles or convert real consoles to use with these virtual pipe organs, myself included. PCs with 64GB RAM and server specs are not uncommon.
you can also spend a lot less and still have tons of fun with it, I personally have 3 cheap midi keyboards, a pedalboard I midified myself and two launchpads and it works great, total expense was definitely under $1,000
In terms of HW I can strongly recommend the Metzeler Silbermann [1], not that expensive and extremely satisfying to play.
As an autodidact I am definitely limited in what I am able to play, but it is still amazing to learn Bach pieces: I have listened to Bach's organ repertoire all my life since I was a kid, but learning a piece shows you a lot more just how amazing the music is.
