This is probably and hopefully my last meddling into economy of this game, but this needs to be said:
Spatial Scanners are not pay to win option, but I am always an advocate, when it comes to matters of choice.
I understand that developers need to make a profit out of this game with them and I am not trying to prevent that.
I just want to add an additional option of making them craftable, by using in game Invasion resources.
However, since they are craftable, cost should be really immense.
In the long run it would be much better to buy them for a full price or on 50% sale, at least.
What matters the most, is the option to craft one.

Examples:
Tier III Spatial Scanner requirements:
Tier III mark IV Enhanced Sensor CPU component
5000 Iridium/Artifacts
500 Monocrystals
250 Processing Blocks
250 Screened Batteries
250 Osmium Crystals
Price: 3000 GS (optional crafting price: 30000000 credits)
Tier IV Spatial Scanner requirements:
Tier IV mark IV Enhanced Sensor CPU component
10000 Iridium/Artifacts
1000 Monocrystals
500 Processing Blocks
500 Screened Batteries
500 Osmium Crystals
Price: 5000 GS (optional crafting price: 50000000 credits)
Tier V Spatial Scanner requirements:
Tier V mark IV Enhanced Sensor CPU component
15000 Iridium/Artifacts
1500 Monocrystals
750 Processing Blocks
750 Screened Batteries
750 Osmium Crystals
Price: 6000 GS (optional crafting price: 60000000 credits)
Resource cost is well justified. If it’s too high, it should get changed or lowered.
Developers can either change the type of resources and maybe even the numbers.
I will leave this in their capable hands.
All I am asking for is to make them craftable. Resource cost is yours to decide, but it should be immense.
It should be more than evident, that it is much better to pay for the Spatial Scanner, than to craft one on your own.
Since it’s still possible to accumulate such high amount of resources, I still do recommend this option, if you’re out of money and not out of your resources.
