If your computer came with Windows 7 pre-installed, it is likely out of warranty so it will not be free, but.....
Try contacting the Computer Manufacturer and see if they can provide you OEM Recovery Media. There will likely be a nominal fee but cheaper than what you are considering.

You computer should also have a COA on the side, back, under the battery (if laptop) with your product key.
IF you can get your hands on the same version of Windows 7 (Home, Pro, Ultimate, etc.,) and same bit architecture (32 or 64 bit) then you should be able to reinstall Windows 7 using that product key.
It will take a phone call to MS to activate, but worth the time and effort.
