Grooveboxes, workstations and more!

I've been thinking about getting a new groovebox for a while now... Actually I didn't know what they were called until I saw that first post on this community then it all clicked! (Thanks btw!!)

I've played around with an old kaossilator and it was pretty fun but I'd like something I can maybe put my own sounds in? If that's generally a really exorbitantly priced feature then I can skip it.

Any suggestions on where I should get started?

Thanks in advance!!
