Was tempted to get the Death Star planetarium until I read the reviews at Toys R Us. Apparently it's not a planet destroyer, it's a battery and light bulb destroyer. People are changing the batteries AND light bulbs nightly.
Also, it is only $19.99 at both Toys R Us and Walmart. After the typical Toys R Us 20% off coupon it's only $15.99 in store pickup.
I'd be willing to give it a try and hack it to take better light bulbs but not when I can easily get a lower price from a major retailer. Beat the price woot and I'll buy one.
