Julie, I'm sorry - I didn't mean to imply that you didn't buy a tet conversion - I was trying to say that I don't think tet conversions of it were common back when I was reading about it. John Benz, in the link I gave above, does not say when he was experimenting with the "regular" and Tet versions. I do recall that I didn't pay much for Ed Murray when I was using it - so I'm reasonably sure I didn't have a conversion.
