Jean,
You may want to price check those sinks through M&M Metals in Texas. They are far more DIY'er friendly than most other places...unless of course you can find surplus sinks. Their site is www.mmmetals.com

I just meant that with that paticular heatsink, you will be getting 0.25dge/w dissipation, however, conrad do a flatbacked heatsink with a rating of 0.21deg/w which measures almost the same, but is 350mm long instead of 300 (althought this is a tiny bit more expensive at an extra 5 AUD).

bigparsnip ,

Gotcha ! Maybe i'll go for the 350mm heatsinks instead. I just don't know how much is going to be enough per amp with default voltage and bias.

Maybe someone else can shed some light on this ?

Well, I got a quote from Conrad on 4 35cm by 15cm heatsinks shipped with FedEx air , came out to $221 which isn't bad at all.
