I buy from them often, and have actually parked my mill for about a half year now. I took a gamble and had them mill some grains and yeah I think it's been perfect. Looks like my own mill with a .030" gap set with feeler gauges. Efficiency didn't change a bit either. I've converted to having them (him) do it every time now.
And you might know, but if not, if you choose SpeeDee delivery it's arrived almost always in 24 hours. Place an order today, it'll ship tomorrow, and be at your house the next day. And you can order with the option to ship on a Monday, just in case.
