Is Revenge Good?

I got scammed by some thrift shop owners that sold me a Skylanders pack telling me that it was complete and almost new, I then quickly found out after buying it that it was missing stuff.

After some months I went on Ebay to buy some more Skylanders and videogame stuff including a 20euros used Xbox 360 slim. When It arrived I found out that the disk drive didn't work properly and that the games that worked often crashed and showed a lots of graphical bugs. I was fucking pissed. 

Now I'm planning on reselling the Xbox stuff for some PS3 stuff since my PS3 is very good, but I also want to get some revenge and I'm planning on reselling the Xbox for 40euros in the thrift shop from before and in a way scam them back. Is it a good idea?
