These trash cans look really great in a modern kitchen.  The design is simple but smart.  Get the trash bags that are made for these cans... makes it so easy to change out.  Only negatives are that the stainless steel dents somewhat easily and they aren't cheap.

Pros: Sleek look.  Smart design.  Custom made trash bags that fit perfectly.
Cons: Stainless dents easily, but all stainless trash cans have this problem
