[sdiy] Looking for a multimeter

so I was looking on Mouser and found (Mouser) part# 279-YR1B100KCC

100k 0.1% 15ppm/C 0.25W axial through-hole resistors: $0.451 each in
quantity >100

I think adding a reasonably nice meter to your bench is still worth it, but
on the other hand you've apparently been surviving just fine in DIY without
one...
