If somebody wants to spend that much money on a video game then all the power to them, but it sets an absolutely ridiculous precedent and market value for rarer titles--which, ultimately, negatively impacts other TG collectors.
Personally, I get the most joy out of finding rare titles and accessories for a bargain than simply clicking "Buy it Now" once something I need pops up. But hey, at the end of the day we're all free to do whatever we want.
