At the upper end (pricewise), I’d consider Heartland Harps Sylvan (36 strings) or a used 36-string Dusty Strings. Also a used Josephus Harps 38-string model, probably hard to find. I like the Heritage model, but you might like the Dayspring model (more Celtic) better. They also have some smaller, less expensive models. In the middle, R Harps Merlin model. This is not solid wood all through, but it has an awesome sound. At the lower end, there’s the Dusty Strings Ravenna 34 and the Heartland Harps Dreamweaver (34 strings). At the lower end these are mostly glorified plywood, but well-built and will do the trick. I think the Ravenna is unattractive, but it comes with options that

If you visit Harplust List, you will get the URLs for all of these and more and can see them and in many cases hear them in situ or on YouTube. You don’t say where you live. All the ones I mentioned are U.S.- or Canada-based. It makes a difference in terms of shipping costs, taxes, &c. Also check exactly what they’re offering: case or levers or extra set of strings thrown in? Size: can you fit them in the trunk of your car? Do they only become floor harps when you put them on a stand or you sit on a very low stool? Do they use strings so expensive that a replacement set becomes a problem? What is the string tension like?

Here’s one that’s not on the Harplust List: Gerhard Wanney of Thetis Island, Canada. Unusual Celtic-style harp. Also within your budget only as a used harp and hard to find as such.

Don’t know much about them myself, but Thormahlen Harps and Blevins Harps come well-recommended by other folks on this list.

Can you tell? I’ve been shopping around myself.

Forgot to finish a sentence in first paragraph. If you pay a little more, you can get the Ravenna in all black. Still more and you can get it in burgundy or green.
