The ryobi reps just put out the latest 6" grinder when I was at the store. The color is not my favorite. A bright lime green or the like. The led light is nice. I think the price was $30-40 but maybe add $4-5 for a can of spray paint.
I only noticed since I had just walked down the aisle minutes before and the dark blue grinder was displayed.
If you do do self checkout and buy spray paint the system sets off alarms to show an id. If there's no one there though I just continued checkout and no problems.
