I'm glad standard series have plain black as they are good for building roofs. But I don't mind printed ones for licensed series, especially if just a logo Ike this. They'll be handy for decorations in mocs.
You already have to navigate through Bricklink stores that sell used-smoked infested parts.
If you are buying relatively modern parts, I find it easier just to restrict searches to new. New does not always cost that much more than used and you avoid the smelly, dirty, broken parts that some sellers think they can get away with by calling it used. It is not so bad at brickowl as at least there is some grading there whereas at bricklink used can mean anything from used once by an adult through to found in a public sandpit.
