The Asp Scout is not a bad little ship, it just has the wrong price.
A lot of Commanders, when they're looking to make their first big ship purchase out of a Sidewinder or Eagle, are looking for something that they can do a little bit of everything with, light bounty hunting, cargo hauling, exploration, mining, etc, until they figure out what they like most and then buy a specialized ship for it. I was one of those. I call these type of ships Light Multipurpose, and I looked at the Cobra Mk III, the Viper Mk IV, and the Asp Scout. I ended up trying to decide between the Viper and Cobra, and settled on the Cobra because I was uninterested in the Viper's better combat skills and the Cobra was cheaper.
So this is the comparison I made, using a light multipurpose build focused toward long distance trading and beginner's level exploration, with the ability to dogfight my way out of an interdiction.
Cobra Mk III
Viper Mk IV
Asp Scout
Some things that stand out comparing the three in this type of build:
-The Cobra is the fastest in a straight line, and the cheapest.
-The Viper is the best armored and shielded, but is the least maneuverable
-The Asp was double the cargo space of the other two, is the slowest but most maneuverable, is better armored and shielded than the Cobra, and has the highest unladen jumprange of the three.
Now here's the problem. The entry price of the three is:
-Cobra Mk III: 349,720 cr
-Viper Mk IV: 437,930 cr
-Asp Scout:
3,961,150 cr!!!
So when I was looking at these ships, the only thing that deterred me from the Scout was the price tag. When my funds would be at that point, I'd be seriously considering moving on to a Diamondback Explorer, or saving up the funds to upgrade to an Asp Explorer. So to sum up, the only thing wrong with the Asp Scout is the price tag. If it was more competitively priced, I think it could give the Cobra III and Viper IV a little competition.
