Yeah HTML to PDF is a tricky one, presumably wkhtmltopdf/pechkin doesn't work out because of licensing / interop issues? Other than that the only other one I'm aware of is Aspose which is expensive as you say.
Images (along with font subsetting and fixing the gzip implementation) are the next thing I plan to implement so it's helpful to know its a real requirement.
actually wkhtmltopdf/pechkin both won't support pdf/a-3 and have a not so nice output.
aspose is actually really cheap, compared to others, unfortunatly their support is trash: https://forum.aspose.com/t/html-to-pdf-pdf-net-fonts-error-o... i.e. pdf/a-3 does not work on mac (didn't tried linux, but I guess it has similar problems)
btw. itext is a really great library, unfortunatly itext has a problematic licensing and I tought they were jocking after they gave me prices.
