RE: Best Over/Under for around $500?
There are several $500 guns I would seriously take a look at in order from the top:
1. Lanber (contact CDNN.com)
2. Silma
3. Traditions
If you can find a good used gun, you'll prolly get a SKB, Ruger Red Label, Verona. (Browning or Beretta would be too expensive).
