Audiobooks – a question

MrMoleCallsI’ve held off the idea of audiobooks for some time, mainly because I have not found them as easy to distribute as ebooks. However, I have recorded some of them for my own amusement – the Sherlock Ferret series allows me to do quite a lot of silly voices, and also add a little mystery to things.

Here’s a chapter out of Sherlock Ferret and the Phantom Photographer. The whole book lasts for about an hour read in this way.

My question is: how much would you consider paying for a recording of this kind, given that the price for the print edition is US$7.99 or £5.99? Please let me know in the comments below.
