Thank you all! I really appreciate the responses!

I was looking at one of the pages johnvanvliet linked to and it has this line, "Likewise, we specialize in computer-assisted cartography (such as with GIMP, Adobe apps, Campaign Cartographer, Dundjinni, etc.), although many members here also have interest in maps drafted by hand." Which I think sums up the responses.

I had to admit, I've had the various Campaign Cartographer versions but haven't really played around with them because (in addition to their complexity ) I wanted to try the hand drawn route. I did and I really like what I ended up with, but I'd like to try and push my imagination and see the end result, which my current skills just don't allow (although eventually I hope that changes).

Thanks again, and I'll definitely post whatever monstrosity I come up with.
