My local Targets seem to have the toy sets pretty regularly. If you still can't find them,
I have bought lots of stuff from these guys on the Internet, although you'll be paying a small price premium ($22, vs. $20 at Target) and shipping costs, which will not be small because the boxes are big.
The MASS Device also seems
wildly out of scale compared to the other figures, too.
Considering how talkative I can be about things that I like and why, it does bother me that I can't articulate why I still maintain so much affection for
G.I. Joe despite the fact that the show was so bad and the comics really weren't a whole lot better. I really think it might be something like the love my brother-in-law has for
Speed Racer. Deep down, he knows that's a badly animated, really supremely cheesy and dumb show, but his love for it knows no bounds and I think it's because of what the show COULD be rather than what it is. If it hits you at the right age, you fall in love with the show's potential rather than its reality.
Flint's voice actor is on to something, although it's also possible that these are just really really cool toys, too

As Michael24 said, it's going to be a "Best of" collection of 5 episodes from the show.
I like to think that I'm on the fence whether I'm going to buy the other 3, but deep down, I think I know that's a lie
