Coffee's, nee Hammock Engineer, plans + thru-hiker.com's kit are WONDERFUL!!!
As he said, its not hard, there are a lot of steps, and it takes time, but the payoff is FANTASTIC!!!
On thru-hiker there is also a link to yet another DIY guide, but I liked Coffee's better.
Somewhere on this forum I posted the steps for how I got the down in the chambers. That too isn't "hard", just take your time.
