Well, it helps to have a big bank account or to have your parents credit cards....
Honestly, build it to suit what your going to be using it for. If your a mud type of guy, then dont build a rock crawler. If your a mall wheeler, then buy a Honda and get a life...
I have seen alot of guys build ther Jeep to look a certain way but it does not perform how they want it to. I live by the philosphy of "Function before FASHION!!" What good is it to have a Jeep that looks cool and could not get its self out of a wet grassy field??? I am sure that I am opening a can of woprms with some guys when I mention this, but it is my theroy that I go by. And one other thing...you get what you pay for. I know not everyone (including myself) has the funds to go and buy brand new stuff, but be wise when your purchasing stuff and make sure it will work with what your trying to accomplish. My $.02
