Guilty Gear Accent Core Plus European Collector's Edition

Guilty Gear is my favorite fighting game. It is the reason I started playing them regularly/sem-seriously. A.B.A. is one off my favorite characters, so the print is kind of an awesome thing for me. AND I'm a huge fan of artbooks.
But shipped to America this set is $180, when the game itself I could pick up for $20 or $30 easy.

Help me out with this. Is it a HUGE waste of money? Do you think any of the included stuff would be a worthwhile collector's item?

In case anyone was interested, the price seems to be fluctuating routinely between $180 and $185 shipped to the US. I saw it dip ONCE earlier in the week to $166, so I bit.

There are only 18 Lost Archive artbooks left, though, so if you want to get one you really don't have much time.
