I understand it costs money to develop a product, to do injection molding, to pay off greedy ass Disney, and that it's all compounded by needing to do all of this for a limited audience. These are small runs, and you want to recoup your sunk costs. In that sense the costs are what they are. I'm working on something now that I'd like to eventually sell, and while it won't be $500 it probably won't be cheap because costs are costs are costs. So I'm not getting out the pitchforks.
But ... for $500 I expect a product that has thought and attention put into it. Regardless of the costs of the molds etc, if you're selling it for that much you 'owe' the buyer something, imo. And on the list of "things to put thought into" are get the shape of the freaking centerpiece droid right. Good lord. This is one of the most iconic Star Wars characters of all time. And I know that's an overused word, but effing hell, it's R2D2, if he's not iconic then what is? I'd never want to look up at that squashed thing, it's hideously out of proportion. It's just flat out wrong.
Unless that's fixed I can't see why you'd want to buy this, unless you're not really a Star Wars fan and just want something to stick on a pinball you happen to own.
