You have to always work with in your budget, and I respect that. You will get what you pay for when it comes to optics.
I had a Burris compact many years ago that I wish I wouldn't have sold. It was small enough to pack and it worked well for what I needed and wanted. Maybe take a look at the Burris XTS 25 -75 x 70. It might work for you. I have never seen one in person or used one.
I have an older Vortex Skyline. It works for me. If you can save a little more, look at the Vortex Diamondback spotter.
I am a Leupold fan. Check out their Ventana 15-45x60. It is reasonably priced, but I have never looked through one to give you any information.
Whatever you buy, determine what you are going to use it for and look through it first. Determine what range you will use it most at......100 yards, 150, 200, etc.
Are you looking at bullet holes on paper or trying to determine if you are looking at a rock or a deer at an extended range?
Maybe someone can chime in on the above and give you a better perspective. Stick with a name brand so if you have problems you will have great customer service.
EDIT: As I think about it a little more due to the mistakes I made buying optics....look for a name brand with the least amount of accessories so hopefully the money was spent on the glass. Read the reviews, especially the poor ones, chances are these guys knew what they wanted. Decide on angled or straight, a lower power in a cheaper optic will be more bang for your buck, plan on buying a better tripod than the one supplied. Eye relief...do you were glasses (hopefully you wear shooting glasses) and look through it for an extended period of time to check on eye strain before you buy it.
