So here's a thought experiment; what is the cheapest breaker suite we can get, assuming we need to be able to get through any ICE currently printed?
Note that we don't have to break the ice with breakers; if the ice offers a way to get through it without ending the run (such as bioroids or traces) then our breakers don't need to cover those. All we care about is breaking anything that can end our run or trash our programs.
Let's value installed cards at 2 credits (1 for the card, 1 for the install). We'll value Datasucker tokens at 1 credit.
Atman on 0 (5 credits: 3 cost, 1 card, 1 install)
Datasucker with 7 counters (10 credits: 1 cost, 1 card, 1 install, 7 tokens)
Faerie as insurance against swordsman (2 credits)
Total: 17 credits. This setup will get through any ice in the game, although it can't do so with perfect regularity.
Can we do better?
