Hello havenindia
eBay offers RSS feeds for Search results as well as Shops. For the benefit of all users viewing this thread, the help link is : http://pages.ebay.in/help/welcome/contextual/search_rss.html?fromFeature=Search%20Results
The RSS feeds can be accessed from the Search results page (look for the typical Orange RSS chicklet at the bottom of the search results page as well as the Shop page)
For your case, I would suggest that you explore the GetSearchResults API (http://developer.ebay.com/DevZone/XML/docs/Reference/eBay/io_GetSearchResults.html), which offers almost all the filtering options available in Search. You can get a quick PHP / ASP code developed that would fetch your listings and use that information to create an RSS feeds of the listings from the specific category that you want to create a feed for. Here's a link to my post on another thread on the same subject made earlier (http://forums.ebay.in/thread.jspa?messageID=600006505&forumID=300000003#600006505)
Alternatively, you can try the REST API (http://developer.ebay.com/developercenter/rest) which accepts the parameters in the URL itself (& thus saves you the effort of having to get the code developed). Using the REST API also gives you the flexibility to automatically display the results as an HTML page (the API normally returns an XML output) by uploading a Stylesheet (http://one102.fairmarket.net/index.aspx)
I am happy to provide clarification on this if required
Finally, on the choice of RSS feed readers, I am happy using web-based feed readers like Bloglines or Google Reader, for their ease of use & the ability to use them across computers. But, in case you are not online most of the time, then a desktop based feed reader would be more suitable
