You may have overestimated those figures. Here in the U.S. each newcomer inherits his/her portion of the national debt, whilst those who exit early have generally failed to pay their share. Welchers.
But as to the spirit of your post...I've got nearly a hundred of everything, you can't take 'em with you, and I'm local to Watson.
Payment? Yes, received in advance. (His posts, of course, detailing his electronic adventures. I enjoy them.)
I enjoy swapping parts with my buddies at the local -- you guessed it -- swapmeets. Today, for example, a pal boasted he got a coffee can 2/3rds full of 2n2219's last week for $1. I snagged a reel of 74HCT132Ds, some 50 & 100 gigohm resistors, with AD549k fA op amps, some voltage references, polypropylene caps, & a few other gizmos. Total cost < $10.
You can see how it's easy to load up on parts.
Not bought: a 5 1/2 digit Fluke DMM, offered for $25. I hemmed over this one a while, but, already having three of like capability, couldn't justify yet another.
Electronics is fun.
Cheers, James
