elenasgrumpy - While I have no idea what your building skills are and what tools you may have available, I can assure you that you do not need to be a master builder or have as elaborate set-up as Ken to successfully build a 4*-60.
Just look over some of the other build threads here including other 4*'s done by those who had never built before either. Ken is showing a great build but if you don't measure up to his quality, there is nothing wrong with that, You can still have a fine plane. All you really need is a flat table and a ceiling tile and some confidence. You will learn the rest as you go. Ask questions here when you have them, as often as you need to. We haven't charged anyone for our lousy advice yet. Err, did I say that out loud? I meant great advice. As long as you take your time and read and follow the instructions, the SIG kits are rather easy.
