Thanks wallcraft.
I saw your original post when I was researching this issue. To be honest I didn’t really understand it - although it looked like it had a lot of good info in there for people that know eBooks well.
I’m still a newbie when it comes to eBooks and this will be my first non-Amazon eBook purchase. It will be great (i.e., save me $) if I can buy eBooks from somewhere other than Amazon. But I’m still not clear on all the formatting issues and wonder if I will be saving a few bucks only to spend a few hours of trial-and-error trying to get the book converted for my DXG.
