Have you checked with National Hobbies in GA? A few months ago I picked up an O. S. .91 there for around $255, which puts it in roughly the same price ballpark as the K&B. I agree with the rest of the guys... You can't beat the small-head O. S. .91 for ducted fan reliability. It's worth the wait. Good luck! (BTW, it sounds like you have a GREAT family.)
