btw, doesn't his plan look like it will fall over if you breath on it to hard?
The plans look, well... sucky.
But if you have plans that you spend enough time and energy in to make it worth money, then go for it. I wont buy it myself, but if you have the ultimate plans, or you can save time and money because you spent time and money, then go for it..... but remember something, you probably got your ideas from others around, make sure to give back to the community, or just give them out.
