I found a good route for trading rare goods which should net around 500-600K profit per hour. Round trip should net around 1.2 million. I recommend a ship with around 40 tons of cargo with a jump range of at least 13 light years. Fit a fuel scoop to help w/ refueling along the way. I'm running this route to save up for an ASP Explorer. Once I get that, I'm going to set sail for the galactic core, and beyond, for exploration.
Below is the route:
Trip 1 - Purchase the following items at these locations
System: 39 Tauri Station: Porta Item: Tauri Chimes
System: Fujin Station: Futen Spaceport Item: Fujin Tea
System: Geras Station: Yurchikhin Port Item: Gerasian Gueuze Beer (this system takes about 20 minutes to fly to the station as it is over 1 million light seconds from the jump in point- you may skip this run if desired)
Set destination to Zaonce and sell the purchased goods (this trip is approximately 160 light years)
Trip 2 - Purchase the following items at these locations (these systems are in close proximity to each other, so acquiring these goods should be fairly quick)
System: Zaonce Station: Ridley Scott Item: Leathery Eggs
System: Lave Station: Lave Station Item: Lavian Brandy
System: Leesti Station: George Lucas Item: Azure Milk / Leestian Evil Juice
System: Diso Station: Shifnalport Item: Diso Ma Corn
System: Uszaa Station: Guest Installation Item: Uszaian Tree Grub
System: Orrere Station: Sharon Lee Free Market Item: Orrerian Vicious Brew
Set destination back to 39 Tauri and sell the purchased goods. Rinse and repeat. Round trip takes approximately 1.5-2 hours depending on the ship used and jump range.
