Austin,
You need to go after this one if a 1-18 is what you want. I have looked far and wide for a 1-18 to add to my collection and just recently stumbled across one. Mine is just like the one that popped up for you, only coppertone.
$150 is not much to pay for the set, since as others have stated, you can always sell the dryer and get half or more of your money back.
I have learned through experience, especially from buying at flea markets and all types of sales, that if you find something that you really and truly want, and the price is reasonable, you better go snatch it up quick. If you pass it up, and later change your mind, it may be no longer be there when you go back after it.
Go for it!!!!
