The only Celtic harps I see at Lewis Eady non-pedal harps range from about $2,000 NZ and up. One web converter gives $2,000 NZ = $1451 US.

Listings are shown for: a.) Aoyama Pedal Harps, b.) Aoyama Non-Pedal/Lever Harps.

I don't find much information other than a small picture, number of strings, and price, and only Aoyama harps are shown on the website.

Lewis Eady appears to be a fairly typical "school music" shop. It is possible that they can provide some support at the local storefront if that's accessible, and it would seem appropriate to give them a call, and an opportunity to fix a poor setup, if you haven't tried that already.

Lewis Eady may also handle other harp "brands" and may include cheaper ones, but Aoyama are the only ones shown at their web page.

Wikipedia identifies Aoyama as a Japanese company, and gives a link to the Aoyama Company Website which unfortunately appears to be in Kanji with no "translator" button I can find. The pages I looked at don't appear to give much more detail than at Eady, but it's hard to tell without being able to read things.

A US distributor for Aoyama, classicharpsnw indicates "showroom in Fukui Japan," and shows fairly detailed pictures of a variety of Aoyama harps, but mostly of pedal harps. At this link, the bottom left picture (clicked to enlarge) shows a default imagename "the_150.jpg" which more or less matches the "Irish Harp" models at Lewis Eady. The enlarged picture is about 3.5" x 7.5" 150 dpi and doesn't blow out completely at up to about 5x zoom/enlargement. It shows a sharping lever fairly clearly at the top left that someone with more familiarity might identify as to type. About all I can tell is that the mechanism is "roundish" and the levers appear to flip parallel to the strings in a plane perpendicular to the plane of the strings.

If the harp in question is another brand, all this Aoyama stuff of course isn't very helpful.
