I have become a Vortex fan over the last ten years or so. They have scopes that range from economy to high end and believe it or not, they are all fantastic. I've got a couple of the lower end Crossfire scopes on some plinkers, several Diamondbacks on AR platform guns, a scout rifle scope on a Ruger Gunsite Scout Rifle, and a Viper on my long range bench gun. Prices run from mid $100 to well into the $1000s, just depends on what you are after.
For a .30-06, I'd suggest a Diamondback (middle of the road optic) in 3.5x10.

Best thing about Vortex is they have the best scope warranty hands down. I had a Diamondback that I bought from the bargin bin at Cabelas. The crosshairs were canted about 15 degrees. Sent a repair request to Vortex, and I expected to pay for the repairs as I had bought the scope that way. Nope. They repaired it and sent it back to me no charge. A couple years later, I left a pair of Vortex Binos on the tailgate of our side by side (I went to relieve myself in the brush), hunting buddy thought it would be funny to leave me there, so he hopped into the Mule and took off. Binos fell off the tailgate and one of the lenses was broken. Sent it to Vortex, again, no charge just repaired and sent back to me.
