I have to say, I bought one card from Stan, and he upgraded another card for me.
He was polite, helpful and thoroughly professional throughout the whole experience.
Delshay, your attitude on this thread portrays someone who has an axe to grind and personally, I would probably have decided to not trade with you had you been offering a similar service based on that fact.
You may have extra special secret knowledge and that may have been hard earned, but it's not going to do you any good if no one is willing to pay you for that knowledge.
