Looking for advice on oxygen analzyers

Hello everyone. I am looking to find a digital oxygen analyzer for a glovebox that I am currently working on. I was looking at a few models on ebay that seem to measure in the ppm range which is what I want. I was wondering if anyone out there has any experience using these or has advice on obtaining one?
The current oxygen analyzer that I am looking at is

I was wondering if the accuracy decreases over time or if an older used model like this one would still work at all.
Thanks a bunch!
