The trouble is that you've got to pick one or the other, and then, for whichever one you choose, it's ridiculously expensive to get a factory version of the other.
The effect is that Jeep makes it very difficult to have it "both ways."
Personally, I think Jeff's got it right with the Bestop Element Doors. Buy the factory full steel doors, including the power windows/locks if you want them, and then for less than $800 you get a set of half doors that can also convert to tube doors. (The factory halfs can't do that.)
Absent getting lucky and pulling a set of doors off a wrecked Jeep or some such thing, it's the most economical way to have it both ways.
By contrast, if you go with factory half doors, you'll almost surely never be willing to spend the $$$ to get factory full steel doors. Further, there's not many aftermarket options for those (are there any??) and certainly none that will get you power windows/locks without a lot of effort.
