I've got about a dozen of Artizan's Thrilling Tales figures, four or five three packs purchased over the last year and bit. No issues like the OP and others have mentioned, just the usual minor flash & mold lines common to 90% of castings.
Mine were all from various North American suppliers - Brigade Games and the FLGS one city over, FWIW. Has Artizan/North Star changed something in their casting process in the past year or so, possibly not for the better?
Must say I really like the figures - lots of personality, very different feel to Pulp Figures or Brigade's pulp offerings while still being compatible on the tabletop. The various Ungentlemanly Warfare/Dept. of Paranormal Studies packs are especially good - the fat gentleman with umbrella & valise will be heading up a slightly sinister team of investigators as soon as I come up with a suitably scary character writeup in 45A or one of the other systems we use!
