Honestly, id wait for the next event and see what limited time stuff shows up. That said, I've not heard anyone say they're glad they bought Bumblebee Man.

As hard as it is to keep a tight grip on those donuts I'd try and see what's available in the next event as was mentioned above or if you can really control yourself try and wait for Halloween as that's not to far away and usually has some great stuff up for sale.
