Thank you! Could you link the ebay "auction" or name the speicifc type? As he has various ones, seemingly also keeping old auctions of the same items just worded differently.
I specifically didn't want to get the "line remover" one as it's not just expensive but apparently also introduces additional blur (and so far, with my unbuffered one I also don't really see any line to be removed)
They are sold over on Amibay.
