I have no idea whether they maintain it or not, though it's linked to from every company's summary page within Yahoo! Finance right underneath the chart. E*Trade offers a similar feature, and I do use that one.
At the very least, I guess you've found that the Yahoo! product isn't the best ... so perhaps there's a market for your product. Something else you may be interested in is the Google Finance spreadsheet features.
Not sure whether there's a way you could add a hook to send an alert when certain prices are met, but their in-spreadsheet stock prices are pretty slick and very easy to use. Probably not something you could resell, but for personal use, it's a good tool.
