I believe that the Bintel Plossls are just GSO Plossls, so why not buy them from Andrews and save some money. It seems to me that Bintel is always more expensive than Andrews for any GSO sourced or rebadged equipment.
Have a look at the Andrews website:

I bought one of the new 12" GSO Dobs from them and it came with four EPs.
I don't know how long they are going to keep the present pricing on those GSO dobs ($100 less than Bintel for the 12"), it's worth calling them and having a chat.
Keep in mind that the Bintel Dobs are GSO sourced and Bintel badged, there are only those two GSO retailers in Australia.
