I realize opinions have changed but these opinions are due to convenience and available technology rather than operational necessity.
For the longest time and really still today, military long range scopes are generally 10X so that's all you need to shoot out to 1000 yards. It is nice to have greater magnification for clarity and target ID but its a luxury rather than a necessity.
That being said a 1-8 is a great option for medium to short range targets from 3 to 800 yards. The beauty of this package is flexibility throughout the entire envelope of range and there are several man's out there right now, NF, Trijicon, Primary Arms who offer products.
If you still want to go with a traditional hunting/tactical variable optic then the NF 3.5 to 15 with Zero Stop is an excellent option but comes in at a higher price than where you currently are but my opinion on some things, especially optics, is buy once...cry once.
Good Luck
