FYI - My little brother decided to save a few bucks and buy the cheap thinset. All the tiles in his house started popping up 4 years later.

He had to retile the entire living area using versa bond, which I believe is what Trekkor is telling you to use.

I watched my buddy layout my house and it was very interesting so say the least. Because I did not have 1 long wall to work off of, instead many shorter walls and none of them are square to each other, he had changed his mind 3 times. The finished product was great though.
