Kvan- I wanted to add some things without editing my previous post.. again.
Just from my experiences using a cds equipped Leupold scope for the last two gun deer seasons and a few outings chasing yotes as well as sending well over 1k rounds at steel at unknown distances.
Leupold's cds system - overall pretty happy. NOT, I can't emphasize this enough, NOT geard towards the WI woods. Western plains hunting (think range finders) or kd range use is what cds was designed for, known distance engagements.
If you're a stand hunter or sit in a blind over fields with long shots it might be ok. If you like to stalk/still hunt just stay away, unless you're willing to drop the coin on higher end glass i.e. VX5 or better as they have locking cds turrets. Otherwise you're going to constantly be checking your elevation turret. I'm not saying they move too easily but if you're busting thru the thick stuff it will move.. ask me how I know.
Now back on topic. Vortex, if I were looking to add one to a hunting rifle it'd be either the Viper HS or Razor HD LH. SWFA has been selling the Razor LH for $499 on and off over the last few months. However, I think the magnification on the Razor LH tops out at 10x. Imo when it comes to glass on rifles, clarity and quality always trumps magnification. Like someone mentioned before Swaro, S&B, Kahles, Steiner and the like but those are waaay above your price point. I don't think you can go wrong with Vortex as long as you stick to Viper or better glass.
May I suggest one more piece of glass to look at, and imo the best bang for the buck in hunting scopes. Leupold's VX-R, NOT the patrol models. That little firedot is insanely bright, like almost literally stare into the sun bright and it has an auto off/on system so it won't kill the battery. My cousin has been using a 3-9 firedot duplex for the last 3 years and is still on the original battery. I will be replacing my VX-2 2-7 cds with a 2-7 VX-R this year. I personally think you have to at least double the money to get a "better" hunting scope than the VX-R.
Edit: I see the Razor LH comes in a 3-15x model, keep an eye out on swfa. They currently have the 1.5-8 model for $499 and I know the 2-10 model had been on sale for that price too. Also I think Midway has had similar sales. SHOT show is right around the corner and manufactures are going to be moving old inventory soon.
