But what if you aren't the audience for it? The second printing of the books weren't really for people who already owned the books. There were no rule changes - it was all art and layout changes and the inclusion of some errata that you could also find in other places. Which is why I say if it was intended as a cash grab it was a poorly thought-out one because why would you buy the new books if you already had a set?
(I say that as someone who does own both sets. Though in my defense I do both suffer from collector's mentality and have always had access to some great used book stores so at least I didn't buy them new

)
