What Mark said. I also find it useful to remember, before I start installing a moving coil cartridge, that there is a very powerful magnetic field around the little thing and it will exercise serious attraction on any ferrous tools I use. Of course I'm going to be using non-magnetic screws.
It's worth it, learning to do your own setup. I take my time and never plan on getting it just right in the first session. Rough install, rough setup, tuning, fine tuning is how it seems to go for me. Enjoy!
