hi- i have a Maclaren brand rocker, which vibrates but is adjustable- folds quite nicely for storage, has a sunshade and over hanging toys, i used it from newborn and my DS LOVED it, the vibration wasnt like many others was just a light vibration which would send him of to sleep.. Also you can adjust it from laying down to sitting up, rocking or not (great for solid feeding) Think i paid around $120

Good luck on your search
