I found one on KEH.com

The Symmar-S is not the same as Symmar convertible. The Symmar-S is a newer design, but does not cover quite as much as the older convertible lens.

thank you!! I found 2 convertible versions on ebay. I do think the versitillity of the 450 would be nice. I may just splurge and purchase both since they are seeming to be reasonably priced.

If you are going to start this project how are you going to develop the film? I've just started a 7x17 project and am doing tray development. I've described the process and the 'trays' in the November/December issue of View Camera.

For my lens I am using a 360 Graphic Kowa that would have plenty of coverage for 12x20.

Nope, that one won't cover 12x20. 7x17, yes, but not 12x20.

Just pick up the 450 M (save the $$ for film, paper, chemicals and film holders!)

I think you are right. Since I am interested in versatility, I think this will be a great lense for my 12x20. I have found one for sale at a very reasonable price. Thank you for your imput.
