Where Can I Get Replacement Parts That Isn't Pac Parts?

Hello everyone, about a month ago my Casio PRG-600Y fell on the floor, and one of the end pieces broke. I wasn't too happy because the watch is less than 10 years old, and a fall like that shouldn't have broken it.

Anyway, when I took it to a repair place, they told me they don't carry the part, and I should look at pacparts.com . I did as they suggested, found the part I needed and ordered two of them. At the time it was listed as backordered, with a 1-3 week delay.

Well it's been over a month now and nothing. I reached out them almost a week ago about the status of my order and nothing. Even more, when I checked on their site the part is now listed as Discontinued (however, you can still add it to you cart). Needless to say this site is on my nerves and I'll probably be doing a charge back.

The specific part is CAS-10530935. I have found them on eBay, but they are anywhere from $20 - $45 for a single one.

I have also found them on casiopart.com, but question if they are legit or not.
