Make the third choice and invest in Fisher harps. http://www.fisherharps.com/
They are sounding just wonderful, very anatomically cozy and lightweight, much better made and have longer warranty, but for about the same price.
Larry also has got quite an impressive list of 1st grade harpist among his clients.
Pros of 2 you are talking about: might be available straight away and the construction and sound in general is not bad.
Cons: both are pretty heavy. I also don’t like the strings on Dusty – had to play 3 concerts on hired Dusty 36S, got awful bleeding blisters from “rolling” bases.
I played both models you are talking about, and Fisher seriously beats them up on quality and sound.
