Okay so I've been remembering this show from way back lately and it's killing me because I can't think of the name.

Here goes a brief description:

There's three people on a spaceship near earth (I think they're like miner's or something like that) when something bad happens and they find themselves in another part of the galaxy. They then meet up with an alien that takes them to a black market planet and buy's weapons for the three science mech's that are aboard their ship. Then a galactic alliance like people show up on the planet and they end up fighting them with their science mechs turned war-bot's. I know it's nerdy but if you tell me it would be of help.

Buck rogers?
