not very useful...I only ever bought level 3, so there is NO way to confirm that any way other than trying and spending the money. I have the question because I may have to save some money and build a part now and another later on, that's all. If the cost of further upgrades is higher than the net amount then of course it will always only make sense to go 0->3
