Exactly. I don't do firearms at all (we have various IMHO ridiculous laws in the UK,
but I do not want to start that debate) and while I have repaired many cars in the 
past, I don't drive and don't, therefore, own a car of any type.

But if you are going to repair/restore something then IMHO it makes a lot of 
sense to have common spares around. It's not like I am suggesting you should
keep stocks of obscure HP custom microprocessors, or even things like 2901
bit-slice chips. But common TTL parts, transistors, etc are used in many 
machines, and if you are going to restore the real hardware you are (a) going
to need them and (b) are going to need to now how they work so you can
trace faults.

One method that works for me is that if you are buying a fairly cheap part, buy
10 of them and put the rest in stock. Or more than 10 if it is something really
