Looking for an affordable western style duster or frock coat

Hey, all. I'm looking for an affordable western style duster or frock coat, similar to the ones worn by Clint Eastwood in High Plains Drifter and Pale Rider, or those worn in Once Upon A Time In The West. My budget is around $100 at most since I'm hoping to keep the overall cost of this costume down. Does anyone have any suggestions?

Here are some example images of what I'm looking for, but it's flexible. Mostly I like the wide lapels on these coats and I'm having a hard time finding any with a reasonable approximation of that feature.





Thank you!

Have you tried looking at Western/Civil War clothing sites? With cowboy shooting gaining in popularity there should be a decent numbers of shops that carry they style of duster you're looking for. If the cost at these sites are too high then I suggest eBay and possibly some Chinese costuming sites.

Edit: I just did a quick search and found that there's actually a wide range of dusters (at wide price range) available on Amazon.
