This Private Label Rights offer seems to be rather interesting, you get a few top products and you get to keep 100% of the commission for every sale you make. So, if you make only 1 sale the products will not cost you anything at all. If you make 2 sales, well, then you are in profit.
I have seen some of the products around, and I think that I have read some reviews as well. As far as I can remember, I think they have been all good.
Take a look at the PLR offer from Jeff Alderson. I am not an affiliate.
Update: You might want to check out the offer from Michael Rasmussen. He is offering the same PLR package, but with a bonus that you might enjoy.
