I just finished racking up 2 - N72 modules that I spent the weekend building. Holy wow do they sound good!!! I have pretty a decent amount of electrical knowledge...enough to put two and two together if a problem arises, and I have a good amount soldering experience. I'd say that for the complete beginner they wouldn't be too hard as long as you practice soldering with a decent iron/solder combination on some perfboard from Radio Shack, and that you are very patient. I devoted an entire weekend to it and took lots of breaks so I didn't feel like I had to rush. When I first looked at the PCB I thought "holy $*^t are those pads tiny" but it was actually quite a breeze...a few tight spots, but nothing difficult if you take your time. To those who are afraid to spend the money and screw it up....don't worry...Tim is the f'ing man and was able to answer some concerns of mine really quickly. Also, the N72 wasn't too bad. I've built stompboxes that were harder. Two thumbs up...I thought I'd just pass along my experiences for potential SCA patrons.
