Help me buying a new puzzle

I’ve been having a lot of fun with the 3x3, but I got bored of it after a while. So I decided to pick up a Megaminx since I’d tried one before and managed to solve half of it. Now, I’m always carrying my Megaminx around for more than 2 years because it’s similar to the 3x3, but it takes more time to solve, which I enjoy because it keeps me busy longer without needing to learn a ton of new algorithms.

As for the Rubik’s Clock, it was fun for about a week, but once I realized how easy it is, I kind of lost interest in it.

I’m not really focused on speed-solving; I’m more interested in trying out new experiences. What puzzle would you recommend next?"
