Royal Guard Helmet Ebay seller question

Hi all,
I know we are not supposed to post Ebay links but I hope an exception can be made to avoid recasters.

I am wondering what anyone knows about these two sellers. Is it okay to buy from either of them, what do you guys think about each helmet, etc.

Thanks
