I agree. Hence I find it a peculiar claim that Encore Devastator could be considered "perfect" when it has numerous flaws/defects in its design/manufacture.
To be fair, you're talking about inflated aftermarket prices. eHobby Astrotrain originally sold for 3000JPY ($38). I find aftermarket prices to be off-putting in general for any toy... but yeah, limited exclusive toys like eHobby Astrotrain would be more prohibitive than others on the aftermarket. But it doesn't mean that the toy was overpriced to begin with.
