While you are waiting for a new tool to come up, play with Joomla and its add-ons - completely free.
It has a built-in RSS Newsfeeds aggregator. Other CMSs also come with built-in aggregators. Joomla is free and comes with many Linux hosts who offer cPanel with Fantastico.
For example, I have an eBay RSS feed that keeps one page updated automatically. In theory I could have a thousand such pages on the site.
I went to eBay and did an Advanced Search and clicked the affiliate tracking information link and entered my CJ PID. Then I did the search and clicked the RSS icon, which gave me a URL such as (I have edited the Aff id with 9s in the example):
http://rss.api.ebay.com/ws/rssapi?Fe...&fss=0&saatc=1
I entered this in Joomla's Newsfeed item URL field and enabled it in a menu, and that's it. The example is on my site, as is one from Amazon and Yahoo news.
