- A fuel scoop (~900.000 for an 3A - not sure if this gets discounted by Li Yong-Rui, so assuming it doesn't)
Why do you assume that? Li yong-Rui's controlled systems provide a stable -15% discount on ALL outfittings, weapons included, and obviously fuel scoops. His systems are therefore the best in the galaxy to fully equip your ships at a huge discount, much appreciated when modules you're looking for cost several millions. Go to Lembava (Li Yong-Rui's stronghold) or Pikum/Aasgananu (best selection of parts available) to equip your ship. As a note, ships are also discounted at -15% there, so your 6M ASP actually costs about 5.2M there (don't have the accurate price at hand, sorry).
/!\ Beware however, if you're going for a trading ASP, it seems that Edmund Mahon's systems offer better prices for hull and cargo upgrades (-20%, vs Li's -15%). So if you want to spare some extra cash, you might want to consider buying everything except cargo and hull parts at Pikum then head to Mahon's stronghold for the final outfitting.
This is the only case where Li Yong-Rui's beaten in discount rates; for everything else, his systems are THE place to go to spare huge loads of cash in outfittings. It's our secret, don't tell anybody I told it to you
Edit
@Carradin: prices vary very much depending of what you want to do with the ship; however, Astarox is right in his estimations as I calculated that a fully upgraded ASP designed for combat could be as expensive as 40+M (insurance not included). So, depending on your ship orientation, this ASP could cost between ~25M (trading) to ~43M (100% combat), with a middle average of 30-35M for a pirate/smuggling ASP... However, don't hurry upgrading everything from the start Astarox, upgrade your ship progressively if you buy it. But in Any case, never buy a ship you couldn't pay the insurance for.
I was also considering buying an Asp as a replacement for my Cobra, but the latter suits me so far so I decided to spare my money and go for the Python straight. When I reach my Tier 5 allegiance with Li Yong-Rui, I'll be earning a solid 50M/week, which would allow me to buy (56M) AND fully upgrade (200M) a Python within 5 weeks' time... Consider joining a Power in PP if you've not done it so far, could help you a lot

Here's a simulation of a basic trading ASP:

You can get rid of the Military grade hull to save money, but the rest is the basics, and as you see, even with a very inefficient fuel scoop like this one your ASP costs around 22-25M (the price provided for the ship is biased, and I count Li's -15% discount). IMO, the ASP is not very well suited as a multi-purpose ship, more of a decent pirate/smuggling ship if you outfit it with a hatch breaker and a cargo scanner at the expense of some cargo space, but it's not the best ship for trading and the Cobra handles piracy missions better (lower profile, lower heat signature, much faster to smuggle in or evade conflict). I'd stick with the Cobra if I were you and would start saving for the Python.
