I use neotats exclusively at the moment, and although I DO have the "purple packer" I'm not a big fan yet - but maybe if I decide to use the larger mags I'll give it another go. These machines have seriously changed my life. I've been using them now for about 18months, and have a marked decrease in hand fatigue, have been able to switch to all disposable tubes/tips, and for ease of cleaning (even though they're all bagged) you can't go wrong.
