Try the RAD peeps out. They are made in Vancouver, WA and are as good or better than the rest. You'll see that the 38 degree angled peep has tubing and an adapter that comes with it, but you don't have to use the adapter and tubing (I don't use them on mine). The horizontal model leaves more room for sting twist and still maintains a hole to look through which is better in a hunting situation. The angled one is great for target or hunting if you've got a string that doesn't move much. Either choice is a good option.
