sounds like you have been having bad luck lately. you could try the fsm Classifieds, or ebay, not sure if you will get the price that you want though. i know what its like to have the parents get mad for the amount of money you spend, if you think modeling is expensive, try model railroading
(sarcasim, its very expensive), mine got use to my spending. i don't see why you had to buy it, you could have never weant back there, or say i don't want them, bye.
true, you could get a airbrush, but could you get a compresser that costs more too? (the current situation i'm in now)
hope you figure somthing out.
