One of my favourite modular lego buildings, $200 is a great price IMO, a lot of fun to build and looks great. Myer used to sell this for around the same price every once in a while during a sale but I think it's out of stock there now.
Shipping is free from Metro Hobbies for orders >$99. I've bought from there online once and had no issues with the purchase.
The store is having other sales too, worth a look.
Edit - it originally showed up as $200 for me but now it says $249. However, they're having 20% off lego using the code "jumboblack" so hopefully you'll get the price reduction anyway.
Edit2 - some people have been able to purchase it for $160 by using the code. Even better if that's the case!
Edit3 - edited price in title to $160.
Says $249 for me?
