If you are in the usa shrimp direct has this nice little dish
(they also sell it on amazon and it includes enough eggs for several years)
-
The pro is that it is easy to use and it 'filters' the shrimp from egg fragments for you (of course you could use encapsulated eggs); the negative is that is low volume (plenty for a breeding pair but not so much for a fish room with 100's of fishes); not design for feeding/raising brine shrimp if you want them to mature into larger shrimps for larger fishes. The price is alittle steep but it does include a jar of eggs - i keep my eggs in the freezer and they have so far lasted 3 years.

Hatchery Dish
This simple-to-use brine shrimp hatchery is ideal for the hobbyist, science fair student, teacher, or aquarist who treats their fish to the occasional live treat. No aeration required. Includes a three month supply of eggs!
