Greg, I have a weed whacker like Jamie has. At a time I used it daily, now I seldom use it, but only because I seldom grind beans.
Mine is a different brand and a little differnt shape, but essentially the same. It has the same shortcomings as Jamie's, but I've always been pleased enough with it.
It's inexpensive enough to give it a shot,
$46.50 at Amazon, free shipping.
I'm thinking it was closer to $60.00 when I bought mine. I bought one for Todd (revsmoke) awhile back, I believe we traded cigars or something. You might ask him what he thinks?
