That would be kellysgreatproducts. I've bought a range of grinders from him, and IMO his Titan models are the best buy. The 4 piece models have removeable screens and the small 2 piece is a great buy. His other 'all CNC' grinders are good but price wise I've done much better here-

Mendo Mulcher's design is a poor one for a fine grind. It cuts through bud quick and easy and is fine for a coarse grind, but even their smallest two piece doesn't do for fine grinding.
Lots of people like a cheap coffee grinder for a fine grind, but personally, I can't get into that method-just personal preference.
Two piece grinders are a good buy, even Space Case. If you want a 4 pc., I've found the name brands like SC, Mendo, Cosmic, etc., to be way overpriced. I'd rather buy one of Puffitup's sifter boxes and a 2 pc. grinder, than shell out the big bucks for a 4 pc.
