Interestingly enough my experience was almost the opposite. The Plan B M15
oscillator uses the pairing LS318/LS352, and unfortunately Micross don't
seem to carry as standard the 318 package used (so as to allow for a drop-in
replacement for a repair I was doing) - not only did Micross quote an MOQ of
10 pieces for the 318, but they have a minimum order value of £100 too. So
then I called Linear Systems directly, and they were more than happy to send
me just 5 off of each - they weren't long in arriving either, and the
postage was something silly like less than $2! The total was just over £38
which I was more than happy with!
