Which SLR Digital?

The plan to introduce a new SLR digital camera needs much more deeper consideration before purchasing with avoiding the influence by a marketing strategy with manufacturer's commercial advertisements.
I have gotten accustomed to working on APS-C image format area in the conditions of smaller picture angel and multiplying focal length to 1,5 times. All the lenses used on EOS mount are ancient Leica designed ones, no variable focal length zooms, so picture angle adjustment is done by moving myself.
Consequently, have I no inconvenience if the image formatting area should be APS-C that is smaller than original Leica format 36 by 24, yes, the image factor does nothing on me.
As for full sized model, it has been obtained already as M9 range finder model with HK and T-El 135mm, Elmarit 90mm, 2 Summicrons 50mm and 2 Summilux 50mm, MD Rokkor 28/2 and Super Elmar-R 15/3,5.
Judging from the standing point of view of the price and the maturity as a reliable machine, 60D is the model to be obtained I think in addition  it has enough interval to be improved as a designed perfect performance?  7D model might be a choice, but smaller size and lighter weight are not the factor to be selected, because the size should be fit on my palm adequately and suitable weight is indispensable in order to avoid camera shake while shooting.  The finder quality should be a factor to be put an emphasis on!
