Ok, I think I've found where I'll be, its the rpg mod listed on the front page of lancersreactor, checkout
www.khaosprime.com, the people on it seem awesome, and it is a changing universe (according to the mod developers/server), such as new/changing systems, commodity price changes, ship re-balancing (proper rebalancing).
And you can still buy battleships (3 different levels per main faction), new commodities, and much more realistic ship prices (10mil for a battleship!, 300k for a rhino - with 400 cargo mind you).
Also, don't hit an asteroid or other ship, it's a lot closer to a real universe

ship collisions can be fatal!
Check it out, the advances are awesome, and everything was extremely stable last night, when I play Freelancer, I'll be on there. The server is passworded, download the mod for more information, and check the forums on the site, its a pretty lively place to be.
