I buy resistors from Mouser. http://www.mouser.com
I always buy the 1% metal film, the 271- series, (271-10K-RC for 10K is
the new number for RoHS non-leaded). These cost 9 cents each, but 2
cents each for 200. Figure it out. You can buy 50 for $4.50 or 200 for
$4.00. If you do any serious DIY electronics you will be glad you
bought 200 and then you won't say, gee I only have two 39K resistors left.
