>>5276964Old Joseph's original release has some bad legs that can break. Try to get your hands on the reissue since it fixes that and adds a few details on Hermit Purple.
If you want punch effects then Dio Black ver. is up your alley but he has a bad batch of poor QC with stuff like legs snapping easily or rough paintwork. You can get lucky on grabbing a good one but you expect the worst when you get him out the box and for posing. Dio has other color ways also and a "Awakened ver." at the end of Part 3.
Also I hear some odd coloring issues on Abdul or Avdol for the reissue but that mostly slipped my mind.
Jotaro is a little rougher to pose since his sculpt will limit things but he's a doable SAS and you got 3 color choices to choose from with one packing green punch effects. Try to get the 1.5 version of regular Jotaro since he packs a soundplate versus the original 1st.
Star Platinum is a solid SAS but after messing around with Star Platinum Part IV it's hard to go back given his better articulation. You got 3 options with SP2nd being the most expensive option hitting an upwards of 9k but it's possible to find a 6k tag. He packs a "OraOraOra" soundplate. Posed him and SPIV a lot and rarely I feel any breakage will happen.
The World has 3 variations and for some reason the 2nd release is vastly cheaper than SP2nd since they both offer large soundplates. The 1st release of The World has the eye issue since some had an eye painted off point. Another thing I noticed from a few anon's is the extended peg may have issues connected to his back with the airtanks attached so shave or sand it down to get a proper fit. Another way was layering with tape if it's too small and the peg hole is larger.
Don't have the rest but generally that's my experience with the Stardust line. I do reccomend to move on to the manga later seeing each part gets longer and you would love the later offerings in this line.
