Alright guys - deep breaths and perhaps take a seat at risk of getting weak at the knees....

Here is the pricing as provided by Steve.
Total comes to $4,278 USD and with some added incidentals (swift costs and exchange rates) total AUD equivalent is $4,901.
Shipipng is an ABSOLUTE killer!
Exchange rate has also moved against us - My Bank today is selling USD at 0.8477 - I should be able to negotiate something better

A breakdown of the costs is provided in the attached spreadsheet - $175 each glass + shipping and packing costs.
Average cost is about $306AUD each backglass - however he has based on weight of the glass (which aparently varies per game)

I am still happy to proceed at this cost.
If this is still to go ahead, i suggest funds should be transferred to my my Bank Acc and i'll arrange the transfer.
