The guy has 1bn cr, and there a people suggesting budget ships?
Seriously, Anaconda or Asp. Asp if you want to enjoy the trip - best view, awesome heat handling, and very agile in SC.
Anaconda if you are trying to get far, fast, and you want to go to the fringes of the galaxy.
Anything else is a compromise, or you're doing it for vanity (a prettier ship), which is fine, but what are your exploration goals?
I agree with everything everyone says here, except for the fuel scoop part. Let me tell you why:
...*scooping stuff*

Here's the thing, the theory is sort of sound... But....
When you are truly trying to make distance, as I am now, where I'm 16030 Ly form Sol, and I just want to get the *expletive* home, the dive bomb scoop technique is slower. The reason, is the time it takes you to get out of the "heat zone" before you can activate your FSD without toasting your ship.
It's actually faster to let your fuel deplete, and then, at about 1/3 of a tank, do the dive bomb technique. To get the most out of it, you'll want the biggest scoop you can get. It probably saves about 10 seconds, but for me, that's about 5 minutes per 1000Ly (I need to scoop about every 6th jump). I've flown 200k Ly on my trip so far...
