I know how you can get a good ship. Go to Pesos and fly south-east for a while untill you get to an abandoned station. You can buy the Dreadnought (powerful!) there for 280533 bars of latinum (less when you buy it for yourself). Then go to Bajora and fly North-west of the planet to a wormhole. The wormhole will take you to Dyson where you can buy the cutting beam from a Dyson sphere (a very VERY VERY LARGE station) for 3072 bars of latinum. Attach it to your Dreadnought and you have a pretty darn good ship. Just try it.
