I've bought 2x DC X 11's from Gulf Coast Avionics without GST as they came seperately and they were below $1,000 so no GST. They usually arrive in 5 days on Fedex economy. Would consider the Bose or the DC at the moment. Gulf Coast have stop stocking the DC's due to some quality issues. Eg, DC sent one to them that had previously been returned to them and it had the previous owners name engraved in it AND it didn't work. Getting lots of reports from owners on the X11's and a few are changing over to Bose, Telex and the Zulu's.
