If you are going to hunt in thick areas that will limit your range down to less then a hundred yards, I would like to suggest a scope that has done great things for me. It is a Tasco Bantam in 2.5x:
It is a very inexpensive scope at only about $36 from Wal Mart. It is a shotgun/BP scope and does work well. It has been on my Sidekick for years and has helped me harvest many deer. It has a standard BP style reticle with a circled cross hair. It couldn't get any less confusing.
For that price you can't go wrong.
