Another vote for Versafine too- although it is true that not all clear stamps are made equal! Some never give a good print, no matter what. 'Wet' inks, like Distress for instance, don't take to the stamp well, they just sit on the surface, and you get a poor print. I did some comparisons here
on my blog recently, it may help you choose. Just ignore the Clearly Better inkpad I compared them too, as I heard yesterday that it is being discontinued!
