Done the X 10-20-30 road and now have the 10 and 30 but not the 20. Upgraded from the 10 to the 20 for the information overlay in the VF but was a little underwhelmed by it - the exposure info is there but can be very hard to see against the subject and the artificial horizon isn't in there. Had sold the 10 to a mate and when I was thinking about the 30, he fancied an upgrade to the 20 so I took the 10 back in part ex for the 20 and put the extra cash my way towards the 30. Mrs Nod prefers the 10 - leaves it in EXR mode and uses it as a P&S but I like the control and WYSIWYG that the 30 allows me to see through its EVF, especially the level! Well worth the upgrade for an enthusiast but possibly not for a pure snapper.
