You've not given us a budget, which doesn't help.
I bought one of these for a very special boy's 5th birthday last year. I didn't see him until nearly two months later though, at his Dad's birthday barbecue bash.
Knowing how quickly youngsters break things, or simply get bored with them, I thought that he'd probably forgotten all about his gift from me by then but, instead, I found him racing around everyone there, determined to show off his watch which could (among many other things) take photos:

So it was definitely a present which was appreciated!
