I use a Bushnell Trophy 1.75-4x32 on my H&R ultra and love it. It's small, light, clear, low powered and cost $100. I'm not going to say it's as good as a leupold, but I have never had any issues with it. And with low powered scopes you don't really notice less than perfect optics. Now if you were talking 9 power and above I can really tell the difference with more expensive optics. The trophy is the cheapest I would go though, and only in the lower power offerings.

The only draw back is I would like it to have a bit more eye relief.
