In the end, going the RC route you'll most likely have to replace their parts with higher quality stuff. If you plan on keeping the jeep for a while, I suggest saving and putting better parts on it the first time around. And replace small things here and there if you have to.
I 100% agree with this. DON'T GO CHEAP!!! I can't say that enough. DON'T GO CHEAP!!! You will regret it.
1. Research your build before you ever start buying.
*what you want out of your rig
*terrain that you will be wheeling
*will it be used on and offroad or just offroad?
*look at what others are doing, many others, lots of build threads out there, then decide what you are capable of
2. Plan your build in stages if you are on a budget.
*Adjustable aftermarket control arms and trackbars can be installed while still stock and adjusted for lift later
3. Find a club in your area and talk to others that have been around a while and see what advice they have. Forums are great but can be skewed with those that have no idea what they are talking about.
4. RESEARCH SOME MORE! If your eyes start to bleed you are to a good start. (not kidding)
Best of luck to you and hope that you are happy when you finally do decide. Remember to be patient, jeeps wheel pretty great stock. Go out with a good group of guys a few times, you will be surprised what a stock jeep can do.
