Thanks guys, already got Cobra and on my way to Type-7. Keeping Cobra for when i get bored of trading and wanna do something more action oriented. I have to agree with one of the posters though. 600 trips to get another ship is just a beginning. You will need a LOT more trade runs to get to tier 3 and even more to tier 4 ships. I consider Type 6 tier 2, type 7 tier 3 and type 9 tier 4. Similar for BH ships ending with Conda as Tier 5.
Aurora - Tier 1 - easy to get. Then the next stop is Cobra fitted for trading you can get 40+, then in about a day or two of casual grinding you can have enough for Type 6. If you like me you'll grind a bit longer to get bigger cargo holds. Now Type 7 it will prolly take me 2 weeks since I barely make a million a night if even that much. Got only 2-3 hours max to play a night and I dont wanna burn out so I try to do fun stuff on the way too. Type 9 costs 10 times of Type 7. Getting ASP before Type 7 doesn't make sense, at least to me, I don't like exploring since there is nothing really to see, pretty much the same template in the same system just colors of the stars and planets change.
And exploring imho is even more boring than trading. While trading I at least imporve faction standing and get bigger missions come up from time to time. Exploring is like doing same repetitive thing as in trading - jump between systems except you push a button or two to activate scanner and then jump again.. Its quite boring since you pretty much just sweep the space for some info that you later trade for credits. Trading at least allows you to break the routine by playing with faction missions, going out of the routine when big missions pop etc.
So back to Type 9. If I dont enslave myself to ED it will take me about 20 weeks to make enough money to get Type-9 if I dont die from boredom first. So considering that I'll do thigns on the side to make things fun, plus family, job etc, I guess about 30 weeks to get Type-9. That's 7 months. I hope I am here for a long haul as well. But then there is a big BUT. I personally can't do only one thing day to day, its boring and I dont wanna burn out. I want bigger trader ship to secure money in the bank since trading is the most consistent way to make money as soon as you find a good trading route. But I also want something better than Cobra for BH eventually and other fun things to do. So you can easily say that average semi-casual player like me will probably spend 1 year in ED before he can even think of getting Type-9 or Anaconda.
I am not saying I want it NOW... but 8-12 months feels a bit like a very long stretch. If they dont improve the game I may never see the conda again. Its very quiet and settle game right now. Need more events, more informative newsfeed, distractions from day to day routine. So I hope as game progresses it wil become more and more interesting with basic core mechanics expanded and new elements added down the road. I mean they need to keep us interested otherwise people will start falling off like dyeing flies

when boredom sets in.
