That's a great price and there are some really cool alternatives to the dead hologram, some of which are already in this thread. A friend of mine replaced his with a bobblehead and some fake plants. Turned out fantastic. Personally I would try to find a nicely detailed model to use rather than the bobblehead, but that's where I would go with it. I've also heard of people putting a small LCD screen down there set up to play a loop of certain movie scenes.
Yea, the hologram is cool, but at the price (and risk of future failure) of a new one, I'd go for one of the alternatives. Besides, having an actual Creature down there is better than a hologram of one any day!
