I explained in my post why I would by this particular "ridiculously overpriced set". I don't even think its price is that bad for what it is and what I as both a Star Wars and LEGO think it represents.
Pretty darn obvious.
I've got a job and I don't have to worry about taxes, bills, housing, etc.
I have a decent savings account built up and use the cash that's outside of it for cool stuff (mostly LEGO because I'm a sad and lonely teenage boyo).
I don't think "nostalgia" is the reason why I am buying this set. Again, it's an extremely well done model of what I consider to be one of the best-looking ships in pop culture. Then there's the additional bonus of getting a few days worth of enjoyment from what I expect to be a fun building experience, the cool new designs that are in the set.
