Welcome aboard
As for your shying away from 5 until there is a supermod - there are lots of mods already that totally change (improve) the game. The excellent modders have done the very hard work, all you need to do is download and install them individually instead of just one big mod. Read the read-mes and the relevant threads and you should be just fine. And for the sake of $5 for the game and some time, what have you got to lose?
