Looking for heatsinks

[mike31154]

You could look around for a place that recycles electronic components, shouldn't be that difficult in a large city. They'll have plenty of heatsinks out of old computers etc. Trick will be convincing them to sell you the stuff rather than ship it off for 'recycling'. I recall when I lived in Ottawa, there was a place in the south end where you could get all kinds of surplus electronics dirt cheap.

Only downside I guess is that your lighting set up might end up looking like something out of a '60s horror movie.
