For roughly $220 or less (they're $209 at optics zone), you should be able to find a Bushnell Trophy 6x18x40AO (Japan). It is a far better varmint/targetscope than anything Simmons, BSA or Tasco has on the market. A buddy had two of them on M700s and was happy with them. Considering all of his other rifles had Leupolds, some of which cost over $700, figure the econo-Bushnellsmust be ok.
Just bought one myself, for $193 on sale last December at a local gunshop (regular price was $214). I have older Tasco varmint scopes that were made in Japanthat have never given me any problems, buthave no use for their Chinese stuff. Thought Tasco might move up a notch after Bushnell took over the name, but havne't heard much positive yet.
