Jungle Cock Capes come in all qualities possible. I have seen some that are so bad that I don't understand how it happens. I have purchased some that are so fine that they stand out as the perfect finishing touch to my work. $150 to $200 is common when you want the better quality.
When you are making a purchase, you want to look at the individual feathers themselves. Notice the splits and the shape. Also the luster should be bright with vibrant colors. You might feel good with a purchase if the look of the feathers could be improved.
If you have some nails that are not up to your standards watch this video and you might be able to save a lot of money.
