I hate to disagree with you, but Dragon Shield are slightly better than Ultra Pro. Much more expensive...
Actually, Dragon Force sleeves retail at $9.99 for 100 sleeves. This also includes a "Dragon Force Deck Box."
Ultra Pro deck sleeves retail at $4.59 for 50 sleeves. The cheapest model of an Ultra Pro Deck Box retails at $2.29.
So, in fact, you are getting the same thing for a dollar and change cheaper. I think it just seems more expensive because you are getting more.
