Its not every day that I can do this but I must humbly disagree with the salukipv1. Not in terms of brand choice but magnification. Are you sure you aren't overestimating how far of distance you need to cover? In my opinion, if I weren't going to get a 60x or 75x minimum power eyepiece, I would just upgrade my riflescope to one of those variable 5-20x, especially if weight might be a consideration.
As far as IQ (image quality), search for a recent string in the optics forum where I discuss price ranges, and pay note to info about extra low dispersion/flourite/HD glass. I'm not an expert, just my $0.02 after having spent more on glass in the last two years than on firearms.
