does anyone know where i can buy a 26 inch wall oven online?

Unfortunately, a wall oven does not come in the 26 inch-wide size. The actual accurate size is then 26 3/4 inches wide. Now it is possible to have 26 inches depth on your oven but even that may vary. My favorite models are without a doubt the GE's.  They feature

• SmartSet controls
  Allow for easy use of the settings. Clock and temperature displays provide added convenience.
• 3.9 cu. ft. oven capacity
  Provides you with enough room to cook large meals for the entire family.
• 2 heavy-duty oven racks
  Create 4 embossed rack positions for cooking multiple dishes.
• TrueTemp system
  Temperature management system helps maintain the ideal temperature setting.
• 8-pass bake element
  Helps distribute heat more evenly throughout the oven. 4-pass broil element for broiling your favorite foods thoroughly.
• Delay-bake
  Lets you start the oven at a predetermined time so you can come home to freshly baked treats.
• Sabbath mode
  Safely maintains a temperature for an extended period of time in order to comply with kosher cooking practices.
• ClearView oven window and interior light
  Let you check on food without opening the door.
• Flush appearance
  Offers a sleek, built-in look to your existing kitchen setup.
