check my earlier thread titled "some websites to get you started" lots of links to sites about this topic.
As far as I know there is no manual or so called instructions as every simpit comes out different. The only thing that really seems to matter with this is what you want and how much money you are willing to spend to get it. Lots of options out there and there is no end to the money you can spend on it. Hope you find something that helps. If you don't find what you are looking for let me know and I will try and find it for you.
Good luck.
