My main worry is that if I do replace the CRT with the LCD then the cab losses any value it had, as it's really just a box with a PC in it at that point.

I have looked all over and just can't find any CRT's that are over 22" as that would be my first option. If I was in the US there does seem to be a supply available for not much more than I paid for the 26" LCD but I can't find anything here in the UK frown

Cheers

Cris.
