They have a lot of autoharps, but only a few used.

They actually have lots of used ones. I've personally auctioned several recently, I won't give my user name as I don't want to use this forum for 'free advertising'. I currently have a diatonic conversion listed and will be listing another early next month, along with several chromatics. Most of mine are in average to much better than average used condition, accurately described, and high bids are usually in the range of $40 - 80, VERY affordable.

Be wary of listings that are short on description, or contain phrases like 'I don't know anything about autoharps' or 'needs TLC' and be alert for inflated shipping charges. A well-packed autoharp should ship nearly anywhere in the USA for $20 or less.

The new ones are MOSTLY Buy-it-now items, so you can filter those out by searching 'autoharp' and then selecting "Auctions only".
