I just had to put my two cents in too.
Use your ability to reason.
Money paid does not assure quality from the seller anymore than the integrity of the buyer.
We live in a market society.
It all comes down to your ability to demand relative to the pool of supply out their.
I can't think of one thing these days that an honest effort doesn't need to be applied to in order to best judge ones decision.
For example, I doubt their are many that will bother to figure out what I'm talking about.
