Muchatrucha,
I realize I'm a bit off of your criteria, but what about a Miroku Sidelock? I recently purchased the below Miroku Model FE Sidelock.
The pro's are: Japanese construction is solid and reliable. They may not think out of the box too much, but the Japanese culture is to do one thing very, very well. They generally copy proven designs - like the Spanish have done, but the Japanese do not suffer from quality problems. Since Japanese guns are not as appreciated in the U.S. as Amerian, English, and European guns, a nice gun can be obtained for a good price.
The biggest con is of course resale. Since Japanese guns are not so appreciated, resale is still not great - but in time that may change.
Again, I realize you've put some thought into your search and question, so I hope I'm not too out of line.
