LM4780 Insulator in aussieland

Hi.

Looking for insulators for the LM4780 in Australia.

Berquist agent does not hand out samples here :( They do sell the SilPad K10 12' x12" at $80.00 + GST (ouch)

I found a cheaper option at RS Components: RS part 403279 Warth K177-NA-30X30 $41.40 300mmx300mm sheet. Link

Warth's www seems to be down at the moment, but it's at www.warth.co.uk Product is electrical insulator, but thermally conductive.

If anyone has any comments or other alternatives, please pipe up :)

Oh, and if any Au diy'ers want to share, I'll have some spare material once I decide which to use, happy to share.
