Well, that's a good problem to have! I would say that you should look at your goals, what's important to you, what you're trying to achieve, etc before you try to pick a toy. I try to teach my son that he should divide up "found money" (birthdays, Christmas, etc).

1)Save some for a rainy day/emergency fund
2)Spend some (gotta reward yourself)
3)Give some to a charity
4)Invest some for the future.

You get to use the "Spend some" now for the gear you want. I'd look at the things that I either don't have, but, are important, or that I do have, are important, and need replacing. In my case, it's my backpacking tent, because the aforementioned son has taken my good one, and I have an old one that I had in college. (Let's just say that was a long time ago). Your answer will be different of course, but, it's about priorities, rather than thinking of this stuff as a toy, IMHO. (But, having fun shopping for toys is part of the deal, fortunately!)
