Component CFFEED / Custom Tag for ColdFusion MX 7?

Question

I work on a client site, and upgrading to ColdFusion 8 is not an option. What I'm looking for looks like CF8 CFFEED functionality with a custom tag or component, and I'm not particularly keen on writing my own reader / parser if something already exists.

I need to read in the RSS2 feed from the blog and display the title, description and link. Preferably, I could set the cache for about 5-10 minutes so that I do not clog the feed (the information that I pull from the feed will be displayed on a site with high traffic).
