I've just finished off the Dvořák sonatina op 100, having played all four movements over the last few months. I love it mainly for its echoes of the other "American" works, including the cello concerto and the New World symphony, which Dvořák wrote around the same time.
I started this adventure by buying a flute arrangement by James Galway, but soon realised he needlessly transposed the entire work as high up as physically possible, which in my ears doesn't sound very nice even if it is played competently, never mind when I try it. So I went back to the violin version (which is free online) and started from that, made it a bit more flutey with my teacher's help, looking at Galway's version for inspiration only where changes were necessary.
You can find a version that follows similar lines and uses the richer colours of the lower register here, played by Julien Beaudiment.
Next up: Albert Einstein's favourite Mozart sonata.
