Oh I agree. But the films are much quicker - only takes about a day of your life in total to watch the whole lot. I also have all the books on audio CD - but listening to Stephen Fry read them all takes even longer than reading them myself (because I read much faster than anyone can read aloud).
When I used to drive a lot, I used to listen to the books while driving - that way I wasn't wasting any extra time - but I don't drive nearly so much nowadays so it would take months or even years to get through listening to all the books again that way.
Yes, I've listened to some of the Jim Dale ones and they're not a patch on the Stephen Fry ones in my opinion.
The Stephen Fry ones are the main ones sold in the UK (e.g. by Amazon.co.uk) but I don't know how easy they would be to get hold of in other countries.
I bought the complete set, on CDs, in a tin: they were quite expensive, but it does take about 125 hours to play the whole lot, so I suppose in terms of pence per minute they weren't too bad You may be able to get them cheaper if they're a download rather than CDs - or you could always pirate them for free via torrent or similar if you can handle the guilt and think that J K Rowling and Stephen Fry already have enough money.
Radio 4 dedicated something like 8 hours to the Stephen Fry reading of the first book, on Boxing Day, many years ago. I like Audiobooks and have several of Stephen Fry's already. HP is way expensive to buy that way though. Even the audio cassette versions are pricey!
I read the first three in German, and I'm reading the 4th now.
I finished the 7th last September. My reading got smoother and smoother as I absorbed more German vocabulary, and I found the 6th and 7th quite easy to read. Overall, I haven't been able to make as much progress in the language as I hoped, probably because I didn't pay as much attention to listening as I did to reading. After I'm done with my master, I might give it more time though (especially watching German scientific documentaries on Youtube, which I find easier to understand). In any case, I will probably start rereading the books in Romanian later this year.
