That's what I need...a good Raptar. So if I get hungry when I'm out with the lens, the Raptar can go kill something and bring it back...

Seriously, I was looking at Ektars and others at Samy's in Hollyweird today, and noticed that most are in Graphic or Acme shutters, and look pretty old. Are these shutters good? Are the lenses easily put in newer shutters, or is that even really an issue with a standard used Raptar or Ektar?
