I thought about acquiring a copy of Roverandom Thornton edition as well, but the current pricing demanded by the secondary market sellers discourage me from ever acquiring one.

I sincerely envy your acquisition of the Roverandom directly from the renowned Mr. Ian Barnes!

I am put off with the current pricing on Thornton Edition Silmarillion as well. The rebinding is done in Morocco (?) using the simplest of the technique with no single inlays. The rebound work of Roverandom fits the book perfectly, but Silmarillion, I have to say it was a lapse in design issue (and cost) on Thornton's part.
