spend as much as you can...

I suggest a leupold vx-iii, or nikon monarch....monarch gold....whichever. Over $200, but worth it. May not need a $1000 scope, but a $500 vs. a $250, is a much bigger deal in my book. Course once you buy a nice one, you'll never again want anything less....

So if you want to buy one for 200 but can spend 300, spend 300 on something nicer. Good luck.
