I think what is hard to understand is spending big bucks on kits and then proclaiming that building enclosures is your hobby and not wanting to buy a cheap $20 router. No offense but it doens't make sense. The N3 has no less than 20 surfaces that need to be routered. 
By all means do what makes you happy, but if you are looking for people to say he great idea go for it, you won't find it here. People are more likely to say Guy thats crazy. Maybe thats ok, but it is hard to understand.
Hi cOz.
At the time when I spent BIG bucks on my three kits, I had the money and a cabinet maker to make the enclosures for me , since then, I have fired the cabinet maker and I am now on a money diet with only a jigsaw.
Now, I don't know where you can find a 20 USD router, because here in Vietnam, the cheapest one I could find was 40 USD and it's a made in China and it looked so cheap that I am not even sure if it could last for more than one project.
No offense taken. However, what does not make sense to you, can make lots of sense to me. Not everyone is the same, think and behave the same, thank God we are all different and that's what makes it interesteing to live on this planet.
As for the 20 different surfaces, I have alreay figure out a way of doing it, it will take me forever, but I have lots of spare time...
For your information, I find everything I need at Audio Circle: Support, criticisms, advices, sarcasms and more... And who are you to say that I wont find what I want at Audio Circle.
If you don't like my funny and intertaining threads, well, just don't read them.
As a matter of fact, I do enjoy the content of your thread.
When Audio Circle members tell me that I am crazy, I like it, because I know already that I am crazy.
