Well,
I don't know if this will help you at all. It might stimulate your interest though.
I can't recommend any cheap coffee at all. Most of them are like using ground sawdust from cheap wood.
Try Christopher Bean's Jamaica Blue Mountain. It's only $7 to $9 for a bag of ground blend or whole beans which you grind yourself. 100% Arabica....... of course, only part of it is actually Jamaica Blue Mountain coffee....... the rest is a mixture of other 100% Arabica beans........ still is mighty delicious.
Pure Jamaica Blue Mountain must run about $50 to $60 a pound. But the mixture I describe above is still mighty, mighty good.
Brewed with traditional hot methods, it's great. Use cold brewing methods, like a Toddy-O cold brew for 12 to 18 hours, it's out of this world.
