Another decent option for your price range is the westin bund center. This falls within your price range most of them time. Especially from now until March.

I know others have recommended Jing'an but my recommendation is the bund area. Depending on your interests it has the city's top attraction nearby and is easily accessible to most of the city including Pudong.

If price is a key factor with the current prices in Shanghai I think the westin provides good value.

Otherwise what are your top interests when you visit Shanghai?
