shrimp net

Hello all! I've looking for a shrimp net.....or 2. Seems like there have been a couple recommended on the forum, but I can't seem to find them in my searches. If you have any good ideas as to where to purchase a good net or if you find particular features desirable over another, please let me...

Was wondering what kind of shape nets you use in your shrimp tanks? There's triangle, square/rectangle and circle ones. Personally I use triangles because its easier to get shrimp in corners and what not.
