Re: power range
How far are you planning to shoot, and how big your targets are going to be? That define the max power you need. <span style="font-style: italic">E.g. people tell of making good steel plate hits at 1000m with 10x fixed.</span>
How close the "short-distance" targets are going to be? Are you considering "tactical" employment of this scope where you may need to deal with multiple targets, moving targets, short-exposure targets (like you need to locate them, aim and fire within a short time interval)? That would define the lowest power you must have.
For myself - considering convenience, comfort and desire for the equipment to be capable of shooting beyond 1500m (whether I'm skilled enough for that or not is another question) - 20x would be the lowest, with 25x preferred maximum magnification (because that's the typical maximum in the available good-quality scopes within semi-reasonable price range).
At the low range - I'd prefer 3-4x, but settled for 6x as that was the lowest available.
So from the list Bob posted - my first preference would be 5-25x, and 5-20x was what I chose as the best <span style="text-decoration: underline">overall</span> compromise - considering power range, glass quality, reticle design, scope quality/reliability and other features.
<span style="font-style: italic">What I'd really like is glass quality of S&B, reticle from Vortex, turrets of Premier, reliability of USO, brightness and clarity of Hensoldt, and finally - cost of Tasco. I'll let you know if this dream comes true.</span>
