I've got a Corona and it instantly upped my efficiency from store crushed (or rolling pin *sigh*) efficiency.

You can buy a better mill, but of course its going to cost you money. (Quite a bit more) All in all, i'm quite happy with the $20 or so I bought it for off of eBay.

A simple variation on this theme:
A 5/16" bolt with a jam nut in the mill, & a hex to 1/4" socket adapter along with a 1/2" socket in the drill. It is a little nicer this way because I can just slip the drill on and off as needed.

My now suddenly ex-fiance (a story suitable for a 3 night epic mini-series) recently bought me a Corona mill for Valentines day. I haven't used it yet but now that we have gone our separate ways I'm considering returning it and using the money towards a roller mill. I guess I'm torn between keeping a mill that is already paid for or spending more $$ on a different one when I don't even know how well this one will work yet.

Keep it. You can always sell it if you hate it.
maybe i'll post an ad:

I've been using a Corona with an electric drill for 5 or 6 years now and have no reason to change. It works great for me.

Here's a tip: To add hopper capacity, cut the bottom out of a 5gal PET water-cooler bottle. Turn it upside down into the Corona hopper (it fits perfectly). Now you have about 24lb grain capacity in your Corona mill.

Mill with drill and "hopper".
Our beverage that art in kegs,
Hallowed be thy tap,
With thee supplied, we will imbibe,
At home as we do in the public house.
Give us this day our liquid bread
And forgive us our spills
As we forgive those who spill upon us.
Lead us not unto hangovers
But deliver us from overindulgence.
Ahh Malt.

Buy a man a beer and he wastes an hour. Teach a man to brew and he wastes a lifetime.

My Corona knock-off with large hopper cost $38 shipped from ebay.
It gives excellent crush. The husks are a little shredded but filtration rate is excellent and eff. if better than store crush.

Get one with the shroud over top of the plates, it will be less messy.

Definitely a decent way to go for mini-mash or low gravity 5 gallon brewers unless you have lots of green.

How long does it take you guys to mill around 15lbs of grain with a corona mill and a power drill?

I'm not sure you could break a corona mill without doing something stupid. They're all cast iron.

I was about to go the route of buying grain in bulk and milling it myself, but then I calculated the cost vs. my LHBS and I decided to not go the route of buying a grain mill.

It seems like the average cost (including shipping) for a 50 lb sack of 2-row is around $65. That's 1.30 per pound. My LHBS sells it for $1.32 per pound crushed. I really couldn't see the need to invest in a mill to save $0.02 per pound. If anyone can point me to a cheaper alternative for bulk grain in the Dallas area I am all ears!

If I were to get a mill, the best deal I found was at Brewmaster's Warehouse. $85 shipped, but you have to build your own hopper and base.
