[sdiy] How available are these parts to you?

[Dave Magnuson]

I personally would choose 13600 / 13700.  Both are available from Mouser:

NJM13600 - In Stock - $0.42 (US) Part number 513-NJM13600D
NJM13700 - In Stock - $0.72 (US) Part number 513-NJM13700D

Each of these is cheaper than a good matched transistor pair (for rolling 
your own OTAs), and still in production from New Japan Radio
