Exactly what I use! Used to be a sort of simplified part of Image Ready, but Adobe have now ditched that in favour of Fireworks. Shame really as I liked Images Ready more for creating web graphics. I find Fireworks a bit too complex and vector based for what I normally need to do. But I'm glad they did keep the save for web mode in Photoshop as I use that the most. A quick Ctrl+Alt+Shift+S shortcut key combination and up it pops.
