What is a good site to find charts with 10 day and 18 day moving averages?

We have not found the ultimate free charting site on the web. We use www.bigcharts.com in our reports to illustrate moves on the averages and some individual charts because it is easy to use. Problem is, it can only show you one moving average. www.investertech.com allows you to run three moving averages at once, and the charts are not bad. We would use them in the reports, but the URL address is too long.
