Your best bet would be comic stores. Call Happy Harbor. Possibly Collector's Edge in WEM, but that place is so overpriced. Seriously, what a joke.
I did well on a limited budget at the PCF. For $45, picked up 4x Cobra BAT, Tiger Force Flint, Battle Armor Cobra Commander, Major Bludd, Firefly (blue), and the reissue HISS Tank w/driver. All loose/complete. I wish I had a little more dough to spend, I wanted to buy the reissue Conquest for only $30. See what they have for the spring PCF... but I'm about to buy some great stuff off HissTank members. And I want LEGO. =)
I'm wondering if that Skystriker is going to show up at retail or not here. I know CBII and I have both talked about maybe going together on a BBTS order to get one, would you be in on that Zero? Cut down the shipping so it's reasonable.
