dwl,
I bought a Sightron fixed 24x earlier this year, just to try. I used it for about 6 months and then decided that, as good as it is, I still prefer my Leupold. (If I didn't already have a Leupold I'd probably buy the Sightron). The two things I think put the Sightron at a disadvantage to the Leupold are 1) optics and 2) elevation adjustment (1/8 minute clicks that lead to the dreaded etherworld of the Second Revolution). Things I like about it are 1) price, 2) weight (comparable to a Leupold fixed 24x) and 3) tracking reliability.
Anyway, I was planning on selling this scope but haven't got around to it yet. If you're interested send me an email (it's on my profile). I think I paid around $300; I'll sell it for $250 (or make me an offer).
