Trying to decide between Cuisinart's more expensive Burr Grinder 12-cup vs their non-Burr grinder 10-cup machine. $40.00 difference. I think the more expensive Burr-grinder model has a larger hopper. Does having a "Burr-grinder" make a difference over a "standard grinder" make a noticeable difference? Or should I save my money and buy the $130.00 model?
