Period Mate is sold for $17 at Amazon. It is similar to Peachlife, but didn't impress me as much. That being said, it still seemed to be of good quality. I tried it, and it worked at least.

Yukki Cup can be found at Amazon for like $12.50 to $32.50 ($20.50 typical) and are a really liked brand. (Again, not one I've tried myself.) Note: the $32.50 is for a pair (one of each size).
