These guys (http://www.maxmax.com/b&w_conversion.htm) are selling B&W conversions of Canon DSLRs - they have the ESO 500D and EOS 550D available to buy, but very expensive.
I believe that they dissolve away the CFA (colour filter array) using solvents - at least that is the approach taken by DIYers on forums I have read. It has a high rate of destroying CCDs though.
If only Canon would produce monochrome versions of their cameras!

They're actually not that expensive for a 15 or 18 mp camera.
Cooling and narrowband/colour filters could be a problem though
Hmm, whats the point you might as well get an astronomical CCD.

Agreed.
What I meant was that if monochrome Canons were available as cheaply as the colour ones (e.g. £200 off eBay) then they would be a force to be reckoned with.
