This ship is retailed at SGD339 (find it pricey as compared to USD179 in US retail) from the Lego shop. My friend bought it at SGD288 (member price) from the local toy store. The price of lego is always higher in Asia as compared to US and Australia. Am considering this set..
At the meantime, here is the clip done by MrTrav71 from youtube on Imperial Flagship. Enjoy!
