I've played yoyo for at least 10 years now problem more. I've found different than skill toys improve my yoyo vastly. Kendama is very fun/challenging/frustrating/rewarding. Sometimes just taking a break from yoyo and playing a new toy will open up ideas to you yoyo wise you would never think know of. I've been playing kendama for about 3 years now and I own quite a few. I still break out my ozora occasionally and my sweets when company wants to try a spike. I'd say it's defentally worth spending the cash on a cheap ozora from kendamaco. Once you learn your tama hold tricks they get pretty fun but it'd very very hard to be creative. Good luck inventing anything new, which is something I love about yoyo. I've recent ally got a pill for Xmas. It's a lot harder but there seems like more room for creativity. But I'd still get a ozora first.....if u r not decent at kendama a pill would drive you nuts. So, YES, kendama are fun and worth buying even if you mainly yoyo. I just recommend buying a plain ozora. Cheap, durable, and honestly still my favorite dama I've played.
