Best Selection Of Individual LED Chips: UVb diodes, 755nm, etc

[Fastarkid]

I found DigiKey dot COM and they do have a big selection but they don't have it all.
Please let me know if you know of a place where I can search through a large selection of individual LED chips...
Or might be better to find a seller of LED chips that are specializing in UVa and UVb for example and maybe a different place
that specializes in 630nm to 800nm (or at least has a larger selection of those wavelengths.
like where I can buy some single diodes/etc.
kind thanks, Dan
