I can understand wanting to feel safe driving with the kids... but I feel compelled to point out that the best (if not only) way to acquire the Jeep adjustment/repair/modification "skillset," is to roll up your sleeves and dig in.
You can get answers to pretty much any questions right here on this forum, and you can find local enthusiasts to help you out with hands-on training. Your boys can get in on it too, and learn skills that just aren't taught in school anymore.
Also, if you think Scrambler prices are outrageous now (I certainly do), just wait and see what they'll be in 3-5 years! You could probably double your money just by parking your Scrambler in the garage for 5 years... although I don't recommend that, either.
Good luck with whatever you decide!
