I picked up an Apple 17" crt display for £1 on eBay last year (local collection). Great display, hopefully years of life left. If you can cope with the bulk and the weight, they still beat most TFTs for price, clarity and brightness. Similar offers for 17" & 21" monitors come up frustratingly often in the London area (I'm in Lancashire - a bit too far to make the petrol worth while!)

I have a Formac 17" crt monitor spare if it's any use (ie within reach).
