Most people I know who bought it will never let it go, or will let it go in about ten, twenty years when only four people would care about it. Otherwise, the best I saw were various price drops and two POs once at EB. It was nice to see it going for $120 or so at the time but even then...eh, I needed to have an XBox to even consider it.
As for the game itself it's like everyone else has already said. If you love mech games, this is more than likely one for you. If not, well, don't think about spending too much. Personally, I'd go up to $120 but since the 360 isn't supporting the controller and since Line of Contact's support has been dropped...there go the major factors for me picking it up. As much as I love mech games I don't want to shell out so much money for a controller that's going to be essentially obsolete with almost everything else.
Shame, though. If Line of Contact had support still I would gladly spend a good amount of money on the game.
