I'm only signing off on a hot tub if it takes me back to 1986. :-P
There's some prizes I can see myself accepting because I could most likely resell them, a car being one of them. I've mentioned this before, but if I win a $90,000 Viper or $50,000 Corvette on Golden Road, I'll gladly sign and resell for a lower price (say $75,000 for the Viper). Even when I take out the taxes, I'm still coming out ahead by about $50K, which is still better than what most shows offer, and the taxes are gone!
I'm not so sure I'd have that same luck on a hot tub or another dinette set. At least I do have a place to store the car...
