Hey there.
my two cents!
If you want something that's more widely available, I've heard Illy whole bean is good, if you like dark roasts. it's on the pricey side, but their quality-control is crazy-good, ensuring consistency.

I've never tried Illy's whole bean through a store. A local coffee shop only uses Illy beans for coffee and espresso. They do in fact make more than just a dark Italian roast. I also buy cans of the pre ground stuff since I don't have a good enough grinder for espresso. I actually prefer their medium roast for espresso over the dark. It is kind of expensive, but very good.
