For $15 you can test the waters. How much do you make in an hour? How long will it take you to design your own web site? In other words, is it worth the $15 gamble to see if someone can come up with something to blow you away?

No, I don't think it is. I could give random people $15 all year long and still not end up with a decent site.

Now, someone who has a history of decent-looking sites is a good gamble.

And it is a gamble, since he says it's non-refundable and no changes can be made.

Agreed -- it's a better idea to wait until he has posted some example $15 designs.
