By cost as in it is an incredible amount of Credits on top of a ridiculous amount of mods. I'm currently half way through Rank 8 and I intend on maxing this mod. It is costly yes, but you only need to max it once ^_^ and my other mods are at a good spot now so I can forgo all production of other mods.
