I'm not decided yet, going to hold out til the end of the month as i'm now considering a DSLR again, so recommendations for an entry level one of those too
For you, or work, with all the grime and oil etc?
I'd shudder at the thought of using an SLR in a heavily dirty environment more than as a one-off. Even if it's weather sealed etc, if you have a zoom lens and the likes it's only a matter of time till you get crud in the lens, body or both
I'm still not convinced too much by the compact-system type cameras (such as the EOS M). They seem to be a bit overpriced for what they are, have a smaller lens selection than SLRs unless you use adaptors, and generally the "smaller, compact size" is a bit of a moot feature as the second you add a lens on to it it still becomes too big to fit in a pocket.
SLR wise work has been using the Canon 1100D without too much issue. Not sure what the Nikon equivalent would be.
