What would you call "mid price range"?

Like binoculars I think you have several price ranges for scopes. You have the 1) Inexpensive ($1-$150) 2)Low to mid range ($200-$500) 3)Moderately expensive ($500-$1000) and then the high end ($1000-$2000).

If you are talking about number two then I would suggest something like the Nikon Prostaff models. Their optical performance and build quality is quite good for the price. Heck, if you can find one of their now discontinued Earth and Sky models then I would suggest them as well.

If you want high end optical performance in the upper mid to moderately expensive price range then check out the Pentax 65 ED model. The scope body sells for $420 a few places online and you can use any standard astronomical 1.25 inch eyepiece with it. Some are as inexpensive as $20 while others can cost almost as much as the scope body itself.

Hope this proves helpful.
