I mean the original pressings for sure, if you are a completionist you will go mad. He had a lot of early recordings that had no distribution and were only sold at live shows, and he was known for recording everything he ever did even if some are pretty lofi. But all the popular recordings are available as repressings, and you can find plenty affordably new online or used at discogs. I’ve never found any Sun Ra in the $2 Goodwill bins but I’ve found plenty of other great jazz records there.
