The investment is worth every penny! Fresh grinding is the key to stepping up your coffee joy! Especially if you can find this kind of not so pricey grinders. Of course, there are some grinders around at the 15-20$ price tag, but as well there are these 1000$+ grinders. I think the 100-200$ price point is a good place to start.
RE: Finally! I got my Sage grinder and now the coffee is fresher than ever. Dabov Specialty Coffee, as usual.
