Well, he seems to have a
decent list of credits to his name and has apparently won a couple of awards for his narration work, according to the bio.
I should add that for anyone who's interested in Tantor's 40% off sale, it applies to both retail and mp3-cd versions.
So if the sticker prices on the regular CDs seem too high and you're willing to live with whatever bitrate the mp3-CDs have been converted to, they're considerably cheaper.
