Here is the Guide of the Perplexed, Friedländer translation 
(Scanned as three separate volumes, the way it originally came out in 1885, with original footnotes.  This, in my opinion, is the best of the English translations, as long as it has R. Friedländer's footnotes. The scan is from Google Books. Google Books is challenging to use but can be made to work. These are very rare volumes. I own one undated from around 1900, with all three sections in one volume, but pagination restarts at each volume, an obvious paste job.  The important and scholarly footnotes by Rabbi Michael Friedländer (April 29, 1833 – December 10, 1910) were scandalously deleted in all subsequent editions.  Here is a click to his Wikipedia entry.  Here are clicks to the Google scans:)

(I include this article advisedly.  Yes, it is biased and provocative. Hakham Faur only presents a single point of view about the 13th Century "Maimonidean Controversy" and attacks many well known figures from that period.  Nonetheless, it is a point of view we never get to hear, and it is very well documented. For those reasons I link to it here.)
