remember you cant shoot what you cant see... i made a mistake by buying a cheap scope and had nothing but problems including missing one of the biggest bucks i've ever seen - i learned! i bought a 30.06 and saved, saved and saved some more (i even sold some crap on ebay) until i could buy a swarovski. i am so happy i did. it was about a 2-1/2 year saving process however every time i had a buck or two i squirelled it away. when any event came up (b-day, christmas, anniversary etc) i'd ask subtley for contributions to the scope fund - yes they are expensive however all I have to say is WOW! The biggest part of the better glass is during low-light conditions. Unbelievable!
best regards and good luck!
