I can't say they're overpriced given the company's size making them. I just can't afford them at this point. I WANT to afford them, and if they got the price under $100 for that walker/tank, I'd probably cave on one. Not both, but one I think would be doable.
They're basically a transformer which is a complex toy when you break it down, so that's what makes me think the price is probably fair enough, I just think it'll hurt sales of the bigger stuff for them.
The 1/16 RC tanks I buy are complex, but they're made by Chinese companies, they're cranked out with quality issues galore (and unfinished which is huge in saving $, and something THESE toys have as a major cost I think), and so drawing comparisons I figure this is probably fair but I just can't justify it personally.
Under $100 and I'd have ordered that thing though. It's beyond cool. It crosses to Star Wars very well (something I feel necessary to buy something outside of Star Wars), and it looks just sooooooo badass and hyper detailed.
