Looking for a new system, Sci-fi in nature, similar to Mongoose Traveller, but with a lot more ship configurations.

Basically, I love Mongoose Traveller to bits, played in a number of games as a number of character types, I'm looking for something similar, something with a lot of personality to the way you play your characters. But the only thing that really saddened me about the game was when I raked in cash from the black market and turned to my GM and said "I want to browse ship upgrades" he just looked me over and said "you can get another turret..." and I stared and said "...and?" just hoping there was more. There wasn't, so by the second session I had all 3 turret slots filled up by the best turrets (of which there are like... 3 kinds) and I just sat on my cash... ended up being a closet homosexual in the end who stepped down from command after I used my cash to buy a young boy and keep him in the cupboard... ANYWAY, point is I want a system similar to Mongoose Traveller (or maybe there are extras I've missed out on??) that allow you to customize your ship, your guns, your armor, etc. So if anyone can point me in the right direction that would be amazing! Thanks in advance! Also looking for a good pre-written universe if anyone knows of one, I love writing stuff but its nice to have a basis :)

EDIT: Anyone know of a good website or something I can use for a good base universe/planetary setup?
