Backsplash

We just have a boring off white ceramic tile backsplash that the builders put in the house before we bought it.  I don't know if it is normal but they grouted all the way down to the counter top and it has since cracked and needs to be redone.  This is one of the reasons I want to redo all of it with some pretty glass tiles.  We looked around at Home Depot and it doesn't appear it would be all that expensive to do but I don't know if it is a weekend project the husband and I can do on our own or if we need to hire someone.
