For what it's worth, I have the Diamondback HP 2-8x32 on a nice .22LR and was quite happy with it other than the fact that it's really a 2.5-8x32 since below 2.5x the field of view doesn't change but the image gets smaller and less crisp around the edges.
On my .308 I have a Leupold VX3i 3.5-10x40 that I think has better glass than either the equivalent Nikon Monarch 3 or Bushnell 4500. Both of those seemed to get cloudy when pointing near a light source, while the Leupold stayed clear.
