I like this one a lot too! As you said, it is pretty much in the same vein as Lenzi/Fulci´s late 60s gialli, except that argentinian actress Analía Gadé is playing the role usually given to Carrol Baker. Piccioni's soundtrack is absolutely amazing, imo. I also have a nice looking Italian publicity guide I've recently bought on ebay. Too bad I don't have a scanner or a camera right now!
The version I have has italian audio and good image quality, not sure where it's sourced from, though - propbably a TV rip.
Here are some screenshots:
