PS: I should note that the M8, or more generally rangefinder cameras, are not everybody's cup of tea --- especially if you are relatively new to photography. However, most experienced photographers I know seem to appreciate the benefits the RF viewfinder offers that distinguish it from an SLR viewfinder; mainly being able to see outside the capture area when composing the image.
It has many disadvantages to the SLR though, and these need to be considered. The rangefinder is very clearly NOT a replacement for an SLR system since it simply doesn't work well with long lenses -- 90 is about the practical maximum, though some folks do press 135's into use; macro is tough due to the imprecise framing and lack of TTL focus; focus is all manual, so tracking moving subjects takes some skill.
But for landscape, most of those deficiencies don't matter much, and the rangefinder process is in many ways like using a portable version of a view camera --- albeit without the lens/standard movements. Plus it makes an outstanding compact and lightweight travel outfit
Bottom line is my advice is to rent or borrow one (or attend a workshop where you can use one) BEFORE you lay out any hard cash for one.
Cheers,
