I have a Leica Digilux, but could not fine it anywhere on tghe dealer spots. I need a memory card for it and its difficult to get locally. The size is larger than the regular cameras.

Amazon could be a help:

It may depend on what your exact camera model is. You have only stated Leica Digilux.
There is the Leica Digilux 1, Leica Digilux 2, Leica Digilux 3, Leica Digilux 4, and the Leica Digilux 5. Most seem to take the SD HC (the SD card may work as well) card:

If your camera is a Leica Digilux 1, then the cards it can take are: Secure Digital Card and Multi Media Card

If you have an earlier camera, then it could take some other kind such as the Compact Flash Card, although I did not find such a note anywhere.
