I bought a largish nylon tool bag to carry the camera, lenses etc. and made some wrappers for the various pieces using 1/4 inch insulation wrapped in cloth and sealed with speed sew. Works just fine, but add it all up and somehow it gets heavy. So I use a jogging stroller to move everything about.
I wouldn't worry about the levels. Mine are mostly dried out (I have a Toyo 45?) and I just got a level from Lee Valley that's about twice the size of a credit card. It works fine and is easier to see and use than the built-in ones.
