Amazon.com has the Roomba Red for $125, however Ecost has a Roomba for $98. Which is the better of the two? The Roomba Red is more but if you go to Irobot.com's site it looks like the Red is lower on the totem pole than the regular Roomba.
It's gotten alot of good feedback at the fatwallet forum and a few other forums I've checked... I'm pretty much just trying to decide which model I'm going to pick up for the missus... I've already picked up everything else for her including the highlight of her christmas presents... a Creative Labs Zen Portable Media Center.
