I've got a Warbot Defender for sale in my sales thread, MISB, with a bonus set of Reprolabels (designed specifically for this figure) to make him a lot more G1, all for $70 excluding shipping. I'm selling it at a loss as since Generations Springer came out, the interest in Defender has dropped significantly. To be fair, Defender is not without its faults, there can be balance and looseness issues, he's a tad short, and the Generations toy is pretty fantastic, even if it a little slender for the character.
I have both figures on display and like them both.
