I hit a lot of different types of toy convention/shows & the one thing I find that is that they are always hit or miss no matter the previous experience. It all depends on what you're looking for & you need to try to take that into consideration i.e. I'm never going to find any TFC Poseidon components in the wild (anybody want to sell some?). So what would you classify as "Holy Grail" material for collection? When I got a DX Turbo Robo I was like "This is it!", but then there was a series of different figures that claimed that title leading up to the current champion. So don't worry about what other people consider a "Holy Grail" figure. You do you & collect what makes you happy.
