I also love the W1080ST for being short throw per se, but the W1070 is practically cheaper. The price difference can be use for custom's tax payment, if you will get it from online store.
It maybe cheaper to buy online than our local store, right? But thinking about warranty of course local store is the right choice.
Did any member in this forum tried the newer HT1075 by Benq? I've also read positive reviews on it.
