Here you go,
http://www.paulya.com/dialerskins.htm, go there and you will find many of the dialer skins. These skins however, do not support smart dial which I never use since I have voice command.
If you want the smart dial, you will have to go with the small picture. I think that there was some work on an Eten skin with the smart dial. I think that you can go to
http://pdaphonehome.com/forums/ppc-6700-xv6700/ and search for Eten with smart dial and see what you get. I think that they had one for portrate but not landscape at the last time I looked. You can also search there for a fellow by the name of KOKOS who has also done some big button skins for the regular dialer but, these have the small picture.
