What about
Feedbooks.com and
Manybooks.net? It's all free and public domain stuff, but it's not all pulp (I think). Feedbooks formatting seem resonably okay to me, and both sites offers customised PDFs.
I make customised PDFs, too. With some of the source material I have, it's simply the easiest way to get a nice looking book, and I don't have a need to be able to change font size.
