Fist lens for M8 - advice please

[ptarmigan]

I pick up my shiny new black M8 in just over a week. Now I need to decide on what lens to get first. I anticipate ultimately ending up with 24 or 28, 35 and 75mm lenses.

So what to get first? I am new to rangefinders so it's difficult to know where to start first.

I also shoot a Nikon D2x and have mostly bought second hand but I'm a little nervous with the thought of s/h Leica lenses as I know so much less about them. Also what about '6-bit' and coding of non coded lenses, can I do this myself or is it an expensive and long wait to send to Leica?

Or can I manage without coding?

Any advice welcome.
