If - as I suspect - the Warehouse uses a national pricing system, then the 8087 TIE Defender will be back down to $29 at your local today, if they have any left.
I was thinking about getting another to build a different TIE with, but the number of shared parts between 8087 and the TIE fighter or interceptor is actually quite low. Still, two figs and 300-odd pieces for less than 30 bucks is pretty tempting...
