The first one is done by a company that I've read isn't exactly top notch and the same goes for the other company on the second link, but the signatures seems very similar to other listings that are more expensive.
Any opinions here are greatly appreciated. Thank you again
Yes, I know - that's how I saw it and quoted the price of $30 which seems ridiculous. I suggest a LOT of research and study before buying anything. Buying based on a sticker or certificate alone can lead to bad things. Post whatever you consider here for opinions from many good eyes.
