[sdiy] low input bias current opamps

[Nathan Trites]

After Mattias and Matthews comments I'll revise my "worse search"
generalization. 5-10 years ago I definitely hated it and would always use
the catalog for reference. I don't have strong enough feelings anymore to
call it worse. :)

Another aspect where I think Digikey is better than Mouser is when it comes
to product photos. Mix ups seem far less common.
