You know, it's funny, I feel this same way about the Freeco Speeder set (which is at the same price point). I found one as a 20% off damaged item in a lego shop today, and I'd have to say it's the most badly mangled box I've seen for sale - looks like it was almost flattened at one point. So if the set is still in good enough condition to sell...that means that the pieces just aren't that big, since nothing was apparently damaged when the box was flattened as it was, which then makes me really question piece count and value. And a 20% off discount only puts it to $20.00 - not nearly enough of a discount for that set to begin with (again reference value), and certainly not in that condition.
Were it priced at $15? OK, maybe then.
