Not to rain on your parade, but have you considered just using a big bold color of paint? I rarely see wallpaper these days and paint is so much easier and cheaper. Big bold color can be fun, even if you do just an accent wall.
@donnatella: We have looked at paint as well, I picked a few colors. But I would like to consider wallpaper too. I found some really pretty options and wallpaper does seem to be making a come back. But overall, it really just depends on our taste and style. When we sell our house one day someone is going to come in and undo the majority of the painting/styling we have done to fit their own taste/style so I try not to worry about that. If I purchased our home based on "ready to go style" we would still be living in an apartment! My house was awful and outdated when we bought it but we have upgraded and changed it to reflect us. I think that's part of the fun of owning a home, making it your own.
