I’ve tried all of the major branded electric harps over the years but eventually settled on the Lyon & Healy Silhouette harp. I’ve found it has some good advantages, but also a disadvantage as well (I’d say the major disadvantage is that as there is no soundboard it’s not possible to rest the hand while playing). There is a good overview of the advantages and disadvantages of the Silhouette harp here. I would definitely try it before buying it as you don’t want to receive something you’re not happy with, or are uncomfortable playing.
