Hi Denny,
YES the Rizzuto is tough! I've been looking for a long time also. I went after that Ebay one but if I remember correctly, it got up to about $250 and I didn't go that high.. Hegan was another that eluded me for quite a while. I finally got that one last week and sure enough, it got up to $80 which tells me it's another one on collector's lists.
Scott, please put me in second place behind Denny!
