Personally I'm more of a fan of minidisc. You can get minidisc players for $100 or so on Ebay and they occasionally show up at the local reuse center for less than that and my experience is that 100% of the minidisc players I've picked up worked (had one fail in six months though...), in contrast to about a 40% success rate with cassette decks. You can buy minidiscs in bulk from Japan for about $1.50 each, which is cheaper than Type 2 tapes. Portable minidisc players are available and can be plugged into your computer via USB to record music with names for the tracks.
My reuse center got two DAT decks, one of which looked terribly trashed, for $200 a piece. Nein Danke!
My son wanted to make a friend of his a mix tape, so I just recently went through the process of trying to get him a tape deck he could record to. Older decks on ebay are dicey, I got one labeled as "tested and working", but it arrived and was definitely not. "LOL, I just copied and pasted another listing, didn't read it". I got this weird deck that looks like the old portable decks from the '80s, but it can record to and from a USB, and once he figured out the right levels and compression settings (audio, not digital), he was able to make a reasonable sounding cassette. We had a lot of discussions about S/N ratios and bandwidth that I never expected to have with him.
Minidisc was where the fun was, it sounded good and the Walkmen were small. I loved that you could edit the md. Which meant if you recorded off the radio, you could instantly have your favorite song on repeat (with DJs talking over the song of course, but it beat waiting weeks before something would be available) - never got a DAT deck because MD was so much more convenient. And then MP3 players came - those with Rockbox were peak fun.
MD pricing can definitely be hit-or-miss, especially on those desirable USB NetMD units. But enough were sold that a little patience all but guarantees you'll find something satisfactory.
There's an active community around MiniDisc these days. r/minidisc and Discord are the places to check. People have been building replacement gumstick Li ion batteries with reasonable quality and there are replacement OLED displays for RH1 and RH10 Sony players. Mechanisms will eventually fail, I suppose, but for now you can still enjoy the format.
On the software end, web.minidisc.wiki has come a long way and there are even projects to expand the functionality of player firmware. Cool hobby, if you're into that.
