Until recently, the only available translation of Solaris, of which a movie was made by the acclaimed Russian director Andrei Tarkovsky (and which some regard as the Russian '2001'), was a purportedly terrible dual translation from a French edition of the book, rather than the original Polish. This new ebook edition is a new translation direct from the source material, as detailed here in an article in the Guardian newspaper last year:

It just showed up from EreaderIQ as having dropped to $1.99 in the US, and £1.30 in the UK, which is pretty good for a book regarded as a bona fide classic of sf. Link:
