This is the F-01-B, within budget, has FTL + lasers + electrobolts with a well-armoured core. It'll chew through anything at its price.
Anything with shields will die to it, because the energy and space requirements means that shields hamper enemy ships too much without giving them a benefit (due to the electrobolts).
It'll get you through amateur space, and some professional ships, but you'll want to upgrade to the slightly more expensive F-01-X before that:

This'll get you through professionals and some veterans. Of course, the next step is F-02-X.

It has the ability to survive that is required of ships when you get to veteran and elite level. You'll want two for elite, though.
If you like the designs, there's a lot more here (https://forum.cosmoteer.net/d/865-armament-intergalactica-faction-wip). Thanks for checking them out!
