No chance to try the Singer.Eastmans have great looking mahogany but ya gotta like the Singer sun burst finish. Have you had a chance to try them out?
You are right, not easy to decide. Problem is that there is no shop where I can try a ukulele of a higher level.I've not had the chance to play either of them but they're both fine looking instruments. I've viewed the Eastman online many times and would love to try one. I also immediately liked the looks and sound of the Singer on TUS. Personally, if I liked the Eastman I owned, I wouldn't part with it for any other uke until I've played it and know for sure that I'd be happy with it as a replacement. Too much room for seller's regret to move something known and liked to replace with the unknown.
Curious for the Singer, Curious and hoping that it is helpful..No personal experience, but from the sound samples I think I might actually prefer the sound of the Eastman. But who knows how they sound in flesh.. people who have tried them I guess!
As for the radius fret-board, have you found it helpful or are you hoping it's going to be helpful?
Because I have to say personally, while I don't suffer from arthritis, as a beginner player I did not find it different on my AMM3. The setup of the ukulele and the choice of strings (particularly lower tension) make more of a difference.
As an older "new" player I've found the radius fretboard makes an enormous improvement in my ability to comfortably shape barre chords. Good for small less bendy hands!On the topic of radius fretboard, it's purely a preference thing and may actually be less comfortable to play if you have absolutely no problems with a flat fretboard.
Speaking from my personal experience, I actually see radius fretboard as a negative feature because it doesn't feel as pleasant to play as flat.
I don't like it how the string actions are on a rounded surface than a simple flat (or slightly higher at the 4th) like on classical guitar.
It disrupts me a bit when finger picking and can't help but the 1st string action 'feeling higher' and the 4th string feeling slanted 'lower' due to the radius.
It makes sense on steel string guitars where you have a bit more tension and 6 string chords to deal with.
On an ukulele, it's a thumbs down from me (and I've owned, then sold off many with radiused fretboards).
I also don't see how it would be objectively better for arthritis than flat.
If you want fretting to be easier, then a lower setup coupled with lower tension strings would be the logical thing to do, not move to a radiused fretboard.
