Do you buy your anime DVDs as boxsets or volumes?

Boxsets, because Pokemon is such a long-running series, it's difficult to collect all the seasons. So the best way to collect it, is to buy the boxsets. They're cheaper too. =)

Most volumes of Pokemon go for about $15 each. And usually, that's only for 5 or 6 episodes.

However, I find it weird that Viz (apparently) skipped seasons 3 and 4. Those seasons don't have boxsets yet, for some reason. And neither do seasons 7 and 8. =O

I even heard that the old Johto volumes for seasons 3 and 4 were discontinued. If that's true, it would explain the high prices that I'm seeing on Ebay...
