Baby swings!!

Ha
So after baby is born and I return to work (about 6 weeks) my grandma (babies great grandma) will be watching baby at her house. 
We purchased a used mamaroo (amazing product btw!!) and I'm sure Gma will need one for her place too, so I'm looking for suggestions of swings to add to my registry (:
Feel free to discuss other child care things on here, that's what it's meant for!! (:
