Harry,
Thanks for all your info!! I think I can convince the "CEO" to let me spend an extra 10%.

Since writing my original post, I have looked at the "Engine Guide" section here on this forum and compared the (3) engines that I listed above against the OS 46AX and found that the OS 46AX had an overall higher rating then the other (3) that I was originally considering. Since I have experience with the OS brand (and have had great luck with), I just might go with the 46AX after all.
Thanks again,
