This could go on forever!!!
i agree, i would count guns for San Sebastian as a spaghetti also, not all spaghettis as you may well know were shot in Spain, quite a few of them were shot in Italy.
Some films even have western elements but aren't really westerns such as the Zanna bianca movies.
End of the day even though this is a "spaghetti western" forum there are many great westerns out there from various countries and it would be a shame not to discuss them occasionally just because there is not an Italian link.
Clint Eastwood for instance has made some of the very best U.S. westerns and in my opinion Unforgiven is the best western made in the last 25 years or so.
Let's just watch our westerns and enjoy them wherever they are from (even though spaghettis are easily the best :))
