That's a really tough call. 180 donuts for a character is a lot. However, if you like the character, and think you might regret not getting him, it may be worth it. His visual tasks are okay, in my opinion, but they aren't spectacular.
I suppose it is possible that he will be re-released at some point and may cost less donuts. That being said - there is no guarentee that will actually happen. If you really want him it might be best to get him now just in case.
