Not as cheap as the recent deals such as $123 from digiDirect via Westfield but they have since raised the original price to $168 (which comes down to $143 with the $25 off coupons currently available) thus making this eBay 20% off deal to be the best I could find at the moment. Combined with discounted egift cards here and you're <$10 difference to best price on OzBargain to date.
