I vote no using our sets. I know some people have made reference to wanting certain sets, including the ones you mention, since we have now opened up PAB credits to include sets.
An idea on this. We pick 1 of our sets (we can discuss) raffle it off the first weekend to test the waters. *If* we get >50% profit from the ticket sales I would say it would be worth our while to use the money to purchase another set to raffle off the next weekend.
OR
We save ourselves the hassle and buy a set to raffle off.
