So I don't like the default ones here are some I created. They are cheaper than the actual costs on purpose. I should note that I have a house rule where you can run a program higher than your system but you take a -1 response and it counts as an additional program for each point over the system rating.

$600 - NeoNET Airwave - Firewall 1, Signal 2, Response 1, System 1, Analyze 1, Browse 1, Command 1, Edit 1.
$1400 - MCT Samurai – Firewall 1, Signal 3, Response 2, System 2, Analyze 1, Browse 2, Command 1, Edit 2.
$3,000 – NeoNET Satellite– Firewall 2, Signal 3, Response 3, System 3, Analyze 2, Browse 3, Command 2, Edit 2.
$6,500 - MCT Shogun - Firewall 2, Signal 2, Response 3, System 4, Analyze 3, Browse 3, Command 3 Edit 3.
$9,600 – NeoNET Lightspeed - Firewall 3, Signal 3, Response 4, System 5, Analyze 3, Browse 4, Command 3, Edit 4.
$16,000 – Renraku Mach V– Firewall 4, Signal 4, Response 5, System 5, Analyze 4, Browse 4, Command 4, Edit 6.

Opinions?

Looks cool. I considered saying something about seperating out firewall/system from signal/response and cut the programs, but then I realized that you already buy a computer with a basically set OS and firewall in it, as well as basic analyze, browse, command and edit stuff in modern day, and that's unlikely to have changed in the future.
