Upgrading?

[.Anubis.1]

Quick question,

So basically I know that its acceptable to keep the starting ship for quite awhile in the game, but I am curious what I should be upgrading. I mean I have the light auto cannonsx2 and a missile launcher but with minimal upgrades (basically avoiding using cubits) how far will this build get me? I am investing heavily with my experience into guns and speed/turn abilities. Will investing in these make a lesser setup work for me? I know I sound cheap but I would love to save up for bigger and better except I really have no idea what that bigger and better should be...

Any ideas?

Thanks,

Anubis
