I jumped from DSLR straight to mono after only using the DSLR for a few months. This was mainly due to the camera that I was using being totally unacceptable. I don't think the capturing of the data is that much different between the two. Mono just takes longer. Actually mono (over DSLR) is easier for me as it can be automated.
If you are concerned about the processing you could always have a go with someone else's data and see how you go. The
Misti Mountain Observatory site has a tutorial and plenty of data to play with.
