I'v been looking at getting some hcpl2531--it seems to be recommended by several people--I don't want a problem with the wave forms like the TB6560 boards optoisolators and then have to fix that. The problem is that most of the suppliers of small quantities of these are in China and it will take two weeks or more to get here. When buy here in the US the prices are way higher. I just tried to buy on ebay from the "Little Diode" store and he wanted $9.95 apeice for them I wanted to buy ten so $95.00 for just the ICs?
I offered $2.50 ea and he came back with $8.50 ea. Should I accept? Or just bite the bullet and wait for some to come from China at $0.50--$1.00 each?

If I'm reading it correctly, Mouser shows various versions of that opto in stock, mostly for $2.50 or less in small quantities, and a price break at 25 units.
