The module is of course a classic. This review is of the print version offered here.
A few complaints:
The maps are not printed on the inside of the cover. Not a biggie, but you really need to be able to separate the maps from the adventure.
The illustration booklet is stapled into the module. Originally it was a seperate book. Again, it's kind of necessary to be able to show the players the illustrations, without having to show the module, or try to keep your place, etc.
Other than these 2 things, I like the printing. Text is sharp and clear, cover is sturdy and has a nice level of gloss. Art looks great.
