This is where I'm at as well, although I may just replace the fluorescent fixtures themselves with ones designed for LEDs.
My first LED bulbs were installed in April 2011. I saved the box and receipt because I wasn't sure they'd last. Since then I've been gradually replacing the (often crap) CFL bulbs with LEDs. I've yet to have an LED bulb fail. I've even started replacing our three way incandescent bulbs in the torchieres with 3 way LEDs because the tech has won me over - sure they're pricey, but three way bulbs are more expensive anyway and don't last long at all.
Except for the kitchen (where the fluorescent tubes are) we're pretty much converted.
Oh, and at Costco I can get three packs for under $15 right now.
