I don't know about the SW 76, but if you want cheap, look at the Stemple 76/.45.
A copy of the SW 76 in .45 caliber. (Hense the name)
They were made by Stemple out of Ohio.
JLM has them for $1595.

I've taken one out. Nice. But, like you said nasty trigger pull. SAR recently ran an article on it.
If I remember, the SW 76 is a copy of the Gustav designed, Swedish K. The Egyptian Port Siad is also a copy.
Not bad for the price. (Although, I'm saving my pennies for a Vector arms Uzi......)
