Our youngest kid is 12, so they're not so much of a problem, timewise. I'll have to send you guys some tools from the states by surface mail. When I enquired about Park tools out here, the basic rule of thumb was to multiply the US$ price by 4! Compared to paying a shop though, some stuff is definitely worth doing at home. By the way, I also have the Park headset remover tool. Makes such a quick job of popping out the cups.
I made some bars once too. Peanut butter is pretty good, but makes it hard to mix. We had a specialty food store that sold all kinds of soy protein and stuff like that. I'd mix all this stuff up, and create a nasty tasting Clif bar, at 3 times the price. That's back when they were 89 cents, so my foolishness didn't last long.
