Default PCB options and sources for LM3886 amp

Hi guys,

There would have to be a recent thread on this but I couldn't find it after a few searches.

I would like to build a 2ch lm3886 amp and was wondering who suppliers pcb's and their quality?

I have only located to sources:
Chipamp.com - I'm told these are well made and ready to go without modification?
eBay - there is two types both are not quite right and require addition parts added off the board and some if the tracks cut to fix.

Surely there must be others?

I'm located in Australia.

Thanks guys - the My_Ref looks nice but I read the BOM is about $150US; which is a bit more than im looking plus I think I would like to start a bit simpler.
Is there a BOM for the chipamp.com stereo kit that includes the part numbers?
I just did an online order to see what it might cost and it came in at $100Aus from element14. Im pretty sure i selected the correct components, some of the resistors came in packs of 10 only which did bump it up a little. I would like to compare my selection against a list with part numbers to see if im on the wright track before i look to shop around.

I also found these boards which looked interesting:
