Well, maybe not in your price range, but with the experience of having had a YJ for 8 years (why did I sell that thing again?) and now a 4-door JKU since 2011, I can tell you that the 4-door is the significant better Jeep in all regards. Mine just crossed the 150k mark and the only thing I had to replace was the starter last year. Otherwise just oils, air filters, spark plugs, and brake pads.
Don't buy into the "3.8 is a bad engine" talk. I've driven the Pentastar in the new JL and it is slow as well compared to any regular car - Jeeps are no race cars and I would rather look for reliability than the x% of additional horsepower on paper which will be eaten by the weight anyways.
My advice would be to avoid going crazy and add 37s, and other most likely unnecessary stuff to it, and rather stay in more "reasonable" areas, such as good 33s and maybe a regearing (and leave the unnecessary camping stuff at home).
With that in mind the benefits of the 4-door (more space inside for people, more cargo space, more stable when wheeling, and yes - a better resale value) are clear, and i would choose a 4-door over any of the 2-doors any time.
