For less 300 bucks you can pick up the following on ebay:
Niikon Team Primos 3X9X40 with BDC reticls - this is the "old" Nikon Monarch - better than Prostaff or Buckmaster
Burris Fullfield II 3X9X40 - I have one of these, bright, clear, reliable
Bushnell Elite 3200, any power range. I have the 4X12 with Ballistic plex reticle on my coyote rifle (.243) and love it. Clear, rugged, rainguard feature really works.
Bushnell Elite 4200 3X9X40. Fantastic riflescope. I see one now on ebay, buy it now price of $249.00. Many people consider this the best scope you can get under $400.00 (retail). Compares favorably with the Zeiss Conquest.
