Yeah - doubling the price does seem a little off...
A moderate computer and slightly lower spec software might keep close to the original price whilst making everything fit?
Say:
Computer 20, MCr 5
Evade/1 (Bandwidth 10), MCr 1
Fire Control/2 (Bandwidth 10), MCr 4
Total: MCr 9
vs.
Computer 5, kCr 30
Evade/2 (Bandwidth 15), MCr 2
Fire Control/4 (Bandwidth 20), MCr 8
Total: MCr 8.03
Adds roughly MCr1 to the price, still keeping things affordable and usable?
