Out of curiosity, what is the plan for sourcing the N900 components? I guess places like ebay/gumtree would be options of course but prices do vary being auction sites. Or are there any stock piles that I am not aware of?

May be a Donation drive for anyone with "Retired" or broken n900s could help with the cause? It would help to minimise the overall cost if we could gather a parts pool. (I would be happy to donate my spare unit)
