Starting a Wreckers collection - but what toys, and where to find them?

As the title said, I'm starting up a Wreckers collection (I'm clearly a glutton for punishment). However, I've hit a snag with several of the Wrecker characters - I can't find toys to suit them and fulfill my toy-collecting criteria (toys must resemble the character I want them to represent and have atriculation at the shoulder, elbow, knee and waist). So I ask you, people of Seibertron, to answer this - which Wrecker should have what toy?
I'll listen to any suggestion, so long as it fits the two criteria above, and if you have better ideas than the ones I've already assigned, I'll weigh them up in comparison. If you'd like to offer a toy for buy or trade, or know where I can find one, please send me a PM! (Note: I have none of the toys listed)
