When you build your aircraft carrier you will quickly learn that that price is not unreasonable.  Not something you would buy to play around with, but if you need it for a shot,  you need it.  If you're a hobbiest, figure how much time and expense it takes you to make yours then compare that to what you make at your job.  $1500 might be a week or two pay, so by buying it you actually save time and money.
