Nothing wrong with Behringer! I don’t own any of their gear though but have often considered getting something that they’ve put out there. The Crave is one I keep considering.
I’ve a Roland SP404 mk 2 and an Elektron Syntakt for hardware drummery stuff, both of which are very current by comparison to those you mention.
The 808, 909 etc very much live on. Even modern machines mimic them. Not that I’d buy any of them to be honest, I’m into more esoteric stuff.
Deciding what I’m going to buy next.
As SUB says the cheap price may mean low quality. The Roland machines have become standard for certain music. Then you have the Alesis SR16 that has been around forever, but I assume it's not that special.
I could just play around with software. I have the Hydrogen one on Linux. Just need to learn how to really use it. I was thinking I could do with a course on music production using such tools as I would like to make more use of them. It would be interesting to make a track entirely with software.
At ModCaf we often do comparisons between Behringer and the official hardware, which is always very interesting. They are often very good but not quite the same as the originals. It depends on what you’re looking to create I guess.
Software is always great and I’m a fan of Ableton and Bitwig. There are some great alternatives in the Linux world.
I think these topics are worth exploring in this community.
There are loads of online courses and planning to create my own based on the knowledge I have.
