That's right, this one http://www.amazon.com/Chromium-Crusher-Premium-Quality-non-aluminum/dp/B000KVBAAI/ref=pd_sim_hpc_1"]Amazon.com: Chromium Crusher 2.25" Premium Quality Tobacco Herb Grinder (non-aluminum grinder): Kitchen & Dining If you're like me, 20 dollars can get you a crappy plastic overpriced POS grinder at your local headshop and you can't seem to find the cheap, nice headshop people you hear about. But I found this one online, and it was so cheap for me I had to get it (I've never had a grinder before). I've got to say I'm enjoying it, and I just got it and already have a bit of kief on the bottom. If you want a cheap new toy to play with I suggest it. It's really solid, I don't see the teeth breaking anytime soon, the mesh is thin enough it doesn't let much more than kief pass through.
Put a quarter on the screen then close it up and give it a few shakes...help push things down faster! Faster=Better
