I have all the six but for DM in Hebrew.
Dune, HoD and Ch:D are by translator Imanuel Lotem(sp?), a well known and celebrated translator here, and are probably as good as the original versions.
Dune,
HoD,
CH:D.
Interesting to note is that while I have a '93 print of CH:D, '96 of Dune and '97 of HoD, the back-cover summary of HoD notes that FH died in Hawaii in '86, and that the next book in the series(CH:D) will
come out soon by the publishing house(it's the same for all six of them BTW, probably for the New Dung too)...looks like someone forgot to update the summary or something.
Also, you can see by the cover design(CH:D's absent from the site for some reason

) that 1+6 are a part of the same, uh, publishing(?), and HoD has a different(more modern?) look to its cover.
Wierd shit going on here.
Not sure who did DM, I think the Lotem did it too, but I can't say.
Cover(and even the summary! what a shitty site they have, and they're probably the biggest publisher we have...also, they've got a nice, if modest, villa, the bastards. the daughter[?] is a Tolkien fan and we once had a gathering near her villa, located near others...one was a bloody mansion surrounded with walls and guards) seems to have been forgotten here as well, though I recall it showing two blue-in-blue eyes looking ahead from behind a reddish mushroom cloud.
DM
CoD and GEoD were translated by some shitty bitch called Dorit Landes(sp?) who is, again, shitty.
CoD,
GEoD.
You know I can't explain myself well in terms of translations and such, but basically I think the vocabulary is lacking, maybe dumbed down, IDK.
There are also some few typos in GEoD(maybe CoD as well) that annoyed me because I didn't find such in the other books.
Seems like the bitch got ahead and at least the Legends series(of which I have two at home *shudder* when I get a good digital camera I might actually film their burning) are edited by her, and translated by some shmuck called Li'or Ben-Dov. Do P&B also use slang in their books?
While looking at the links I found some, uh, readers(if the bloody bastards can even read, which I doubt with these comments) comments...My own comments and clarifications are in brackets.
Here's a translation:
(Of Dune)
Headline: I broke out in the middle.
Body: I didn't like the style. Also, it's appearant the author didn't know much about science and physics compared to other authors- and it shows.
Personally I get more into books by (Stanislav)Lem and Asimov. (Motherfucking twit

)
(Of GEoD)
(Basically he compares his reaction to the book to some character from a popular-with-the-commons low-grade political satire show here saying "I'm disapointed", explaining that while the book reads well, the plot is "lame"(as in limping), stops oddly and doesn't "flow".
"Could've been written better" -well, ain't that what the Hacks are all about?

).
