Well, I recently picked up the final box set to polish off my TOS collection. Its the old style ones, Solid box split vertically. At Walmart they have newer versions in clear boxes that look like they are split vertically. Is there any major differences between these sets? Do they have the new effects put in instead of the original ones (I prefer the original ones)? Are the newer ones a higher quality when it comes to audio or video? More bonus features?
