Good article, Jim! One thing to remember though....

Correct. This article only addresses TC that fit between the lens and an SLR camera body (film or digital). There are no "front of the lens" TCs for SLRs as far as I know - at least none of any quality made by any well known lens maker. Generally TCs (high quality TCs) are intended for use with large aperture telephoto lenses. Even if you could make a high quality "front of the lens" TC, the cost (and weight) would be prohibitive, since for a 600/4 lens it would have to be at least 6" in diameter!
The major application of the "front of the lens" TCs is for small diameter, non-interchangable lens applications on P&S type digicams, where there is no alternative (since you can't put one between the lens and camera body).
