Actually reasonably made sub-20 string harp ?

Does anyone know of any credible makers of a sub 20-string harp WITH LEVERS? I am a professional harpist, but want a very, VERY small harp to bring to my workplace/to small groups just to fiddle around with/take to the park. I have a max budget of $800 and I'm fine with used. Ideally I would like it to cost under $500.

By "credible makers" I mean the likes of Camac, Dusty Strings, L&H - I already checked and none of them carry anything in the string range I want. I already have a Dusty Strings FH36 so I don't need another midsize harp.

Ideal criteria:

- String range around 12-20

- Can be comfortably carried around on public transportation/played in lap while seated

- Doesn't need a cart

- Ideally fully levered, F and C acceptable

- Does not sound like absolute plunky garbage (i.e., Harpsicle)

- No Amazon/Etsy Persian harp scammers

- NO LYRES. Needs to be a Celtic style harp.
