That's a great looking collection. I personally don't collect these because the figuarts are a bit pricey and I tend to prefer articulated figures over statues anyway but bandai now has a cheaper line available so maybe i'll have to start collecting me some dragon ball z stuff.
Speaking of dragon ball z, do you know if wal-mart is carrying the new bandai 20 dollar figures in stores? I think I heard somewhere that gamestop has them but I don't know for sure.
