I think no matter which ever way you go, you should do as much yourself as possible! Financing the rig already done will cost you a lot....... I bought my Rubicon brand new stock; they were asking close to $50k done and set up ready to roll. I am way under that, did the lift, tires, rims my self. I found the rims on line at Amazon, and tires at another online store, I get free shipping and no tax, so the local shop (discount Tires) said they would match it.
I don't think I will ever do Dana 60's so the 44's are ok with me. The front needs to be beefed up with a truss, I was told the backs on the 44 is fine; so figure getting a truss welded on it. (if you plan to wheel) You will with out a doubt need it on the Dana 30, ask T-giv....
I had bought a 2010 Wrangler X prior to my 2013 Rubicon, by the time you figure in; axles, lockers, more power (LS, hemi swap or supper charger) you come out ahead buying a newer one. You will definitely need more power with 35" tires or bigger, if you want to go faster than 65 on the highway with out it being a dog. The 2013 as you prob know has more power and torque. I can say my 13' runs better lifted and 35" tires than my 10' did stock! So if you plan to buy a used one make sure and figure the added cost of everything you are going to need to make sure it isn't a dog; gear swap, more power, axles, lockers, etc.
it all comes down to how much $$$, time you want to spend and what you want to use it for. I like my Rubi, drive it everyday now and wouldn't think of going any other way but that's IMO....... Can't wait to see what you decide, you'll enjoy it either way!
