Pamela, I just did some checking. On harp.com I found the Wheeled Case–Lyon & Healy Troubadour. The item number is 800317, it costs $350. and weighs 15.7 lbs. The Troubadour itself weighs 38 lbs., so when this cover is on the harp, the total weight comes to 53.7 lbs. The wheels that come with this nice case should help a lot! How are you at coping with this much weight? I am a pretty strong male and used to moving a concert grand harp that weighs around 80 lbs. Its transport cover, with all the accessories, weighs around 20 lbs., so I am moving 100 lbs. or more. We use the 6-wheel harp caddy, which is wonderful climbing up and down stairs. My sweet wife is always there to help me, putting the harp in the car and getting it out, opening doorways, etc. I am now retired, so I will no longer have to move this large harp out of my house very often.
The Wheeled Case seems self-sufficient, and I doubt that you would need anything else to easily move the Troubadour. I hope someone else has an opinion about this, and I hope I have helped here.
Harp Hugs and best wishes,
Balfour
