One of the least expensive, and highest quality options would be IQFeed with QuoteTracker. Tier 1 datafeed with good and highly supported 3rd party software app. This setup can start at $20/mo, or $27 if you register the QuoteTracker software.
If you need basic charting and want to watch more symbols (up to 1300) an annual DTN.IQ subscription is $44.50/month and includes Futures, equities, options, international futures as you had with Qcharts. The charting isn't as good as Qcharts or Quotetracker, but it is plenty for most people who want trend lines, moving averages, bands, fib lines, etc.
There are other 3rd parties that work with a DTN.IQ or IQfeed subscription as well, such as Ensign, Investor RT, Wave59, Tradestation, AmiBroker, etc.
