EXIF plugin for Photoshop CS3 MAC version

Hello everyone,

Question: Does anyone know of an industry-standard, reliable EXIF plugin for Photoshop CS3 for MAC? I already have an EXIF tab in my File > File Info tab, but I specifically need a plugin that reads Shutter Actuations from an image. I need to know how many times a camera I just bought has been fired.

Rambling Backstory:

I just bought a used Canon 1d Mark II on eBay, and I think it may have been misrepresented in the auction. The seller claimed that the camera only had around 29,000 shutter actuations.

She based this number on a program called "Cancount." When I received the camera, I took a test shot, and attempted to download cancount. Unfortunately, I ended up on some German web site, which asked me for 13 euros to download it.

Instead, I downloaded the free, and much more detailed Simple EXIF reader for Mac. This program said the camera was closer to 160,000 shutter actuations.

Here's the screenshot:

All I want to know is which program is more reliable, Cancount or Simple EXIF reader. OR, does anyone know of an industry-standard EXIF reader that everyone agrees gives a reliable shutter actuation count? Thanks everyone.

Maybe i am looking at something different here,but i usually check my frame count under photoshops file- info ,and once there i go to advanced,and under the fourth arrow called http-exif, i can see my frame count. it says aux-image number. not sure if that will help you.
