I would stay away from cheap tile like the stuff at Home depot
there are plenty of decent places around, Boston Tile in Dedham is OK.
http://www.artoftileandstone.com/ Take your wife here and ask for Joe Dimare the manager, he knows tile. I just got my tile from there, (spent half what bigfish spent) He is on vacation next week but the showroom would blow you away. They have regular stuff too. If Joe isn't there , tell Debbie I sent you in.
