I agree with Nino.  In a few days when Greg & Mark are back in the country I would be checking with both.  Make sure you've got the part numbers for all the stuff as I know Mark has a tonne of stuff (literally) listed in boxes with part numbers only.

As for prices - both Greg and Mark offer great prices to aussies and have quality products.  I reckon I would buy at least 95% of my parts from them.
