Hey
Tom
No
argument with your facts there, but have you looked at Futurlec (www.futurlec.com) ?
They
list 1% metal film resistors for $0.20/10 - or 2cents each - the only problem
with them is they take a long time to ship - from AUS or HongKong - not
sure

Now, let us assume that each of these resistance elements is an indiivdual 1% tolerance resistor. Total overall tolerance of the R2R ladder is now 16% (not very good, is it?) 1% resistors cost between $0.15 and $0.25, depending on where you purchase them and how many you purchase 9unless you're puschasing thousands, of course).
