My favorite pastry scraper is from Target--$2.99. It's a great straight edge for cutting bars and batter breads. Target's version has a 6" rule along the bottom edge and is perfect for cutting equal portions.
And, I love Calphalon's baking pans because they have squared edges rather than the normal rounded corners and edges. I get mine at TJ Maxx or Marshall's for $7.99 each, and sometimes you can find them on clearance for as little as $5. I like to take a dessert to a friend and gift the pan along with the sweets.
