I had to update this post. I purchased a Scunci Steam Cleaner from Target and the wallpaper is coming off easily. I've done half a wall already. Thanks Kycha - it's not the one you have but it works great!!!

I was going to rent a steamer for $35.00 for the day and I saw this at Target for $59.99 and I can keep it!
This thing could have saved me hours as I've stripped 3 bathrooms in the last few years and used several bottles of DIF. Thanks goodness I got it for the largest room - the kitchen!
I may even wallpaper some day again and that's saying a lot. Thanks again!!!!!!!! I'm off to strip some more.
