Save your money...
I like Lee stuff, and have decided that their Perfect Powder Measure is as good as any on the market at any price. Laugh if you like, but when you've got a 20 dollar measure that'll stay within .1 of a grain with most powders, it's ridiculous to spend more.
The Lee Collet dies will make as good of ammo as you'll make with 100 dollar a set dies.
But that Zip Trim thing is an insufferable joke. Just use a cordless drill.
I was under the impression that it would spin like a gyro wheel when I ordered the thing, but it only spins while you're pulling the string. So you have to pull the string a few times to trim each case. It makes no sense to me...
