Front master cylinder sight glass

[The norm]

I did a search on here to see if anyone has replaced the sight glass on their front master cylinder. I didn't really find anything. So I turned to Google.  I found a few things, but nothing that really tells me about the quality, longevity, and fitment of the cheap replacement sight glasses I see on Ebay and Amazon.

So has anyone here replaced the sight glass? Please say whether you were satisfied with how it turned out and where you bought the sight glass.
I am trying to decide if I can justify the time and effort it will take to fix all of my oem master cylinders or buy new/used trx450r master cylinders.
Thanks Loren
