Go kit ! SIG kits are excellent choice for the quality, precision laser cut and fitting, superb instruction manuals, and great customer support. Good for first time builders. I am completing a 4*60 and it has taught me a lot about plane structures, how to do simple mods (although this is unnecessary), building techniques (how to assemble on a building board, what glue to use, etc), wood working skills, covering skills, and much more. I find it a great stress reliever too, as long as you build at your own pace, setting small objectives for each day (or week) ! You can get plenty of help at RCU during your build (what a great site !). You may need to get some basic tools but get them as you find the need.
