Starsiege pc game

anyone know where i can get a copy of this game new on the cheap.

i just got a asus g73jh from best buy so its 1600x900 but not like theirs any difference on a small ass 17in screen. but whatever i had this game back in the 90s when it first game out and of course my computer back then barely handled it idk if they measured fps back then but i probably only got like 25 or so even so it was a cool ass game.

but its been since it was new that i last played it and want to get a new copy. and is there any other game thats like starsiege only newer but still where you drive those droid things and change your weps out.
