About to have Zero Point Mk 3 in 12k research. After reaching that level I estimate the cost will be around 50 million each. My question is simple. Since I am level 87 and the cost of this monster will break the bank, should I continue researching till I have the Charge +18 or save up some money before going on?

What is the research cost for the +18 item and what is the 'credit' cost?

I'd personally keep researching. Just because you can't afford it now, doesn't mean you won't be able to later. Spend some rank points on cargo if you need to and cash in on your mining planets. I've got 180 million in the bank at the moment and I usually earn anything up to 20m per mineral haul. You'll get enough money soon enough.

Money isn't really that big of a deal -- will have enough prior to getting the +18's just that the upkeep is killer ha.
