Brian - not sure if it's a warehouse find or another run, but they're the exact same toys that have been reissued a number of time but in this case from TRU. They're nearly sold out on bbts so might want to move quick. Not sure of how many they actually had to begin with.
Prime's stacks are hacked and that just bugs me to no end, but you can find longer replacement ones online to fix that. Soundwave has the double door - I don't mind it but might bug you. I'd wager you can find them both cheaper if you put some work into it, but its really not that bad of a price especially considering today's increasing toy prices.
Look here for a recolored Soundwave, Blaster & 5 tapes. That's expensive...http://www.bigbadtoystore.com/bbts/product.aspx?product=TAK11566&mode=retail
