I hope you're not considering trading in all your Canon gear and switch to Leica?
They are two very different systems, both with their weak points and strong points. If you have never used a rangefinder before the switch may be more difficult than you imagine, so i would advise you to try (and then try a little more) before you buy. Don't sell your Canon gear just yet...
I use both systems but find myself using my Canons when i don't know what to expect on an assignment because i feel more comfortable with my SLR's.

Good luck,
