This is a decent 15M build if you absolutely have to fly around in an Asp and do combat missions:

Tbh, the Asp takes about 40-50 million to properly outfit for combat, and even then it's only "OK" compared to a Cobra or DB Scout since it has just 2 extra small hardpoints and slightly better power distribution. The bigger ship has more armor and shields, but it is also A LOT easier to hit, so they don't help much.
Where the Asp really shines is as an explorer vessel, or a rares trading ship if you're into that kind of thing.
