Decent soprano ukuleles for under £200

I've been looking around the internet for a few weeks for a new soprano ukulele. My current is the Tanglewood Union Pack (which cost £30)I find it has isdues with staying in tune and it sometimes has a strange sound (though that may be due to the nylon strings. The strings and fretboard are also beginning to look worn from playing. I've decided to spend more money this time so I can hopefully get something better. My limit this time is £200. There are so many different brands of soprano ukuleles and I'm not sure which are the best to go for given my budget. So I just wanted to ask if anyone can recommend a soprano ukulele under £200 as that would be a great help in my purchase.

Thank you!

a very best one (and I own and have had beautiful sopranos : Kamaka vintage, koaloha, Martin vintage, Anuenue 1879...) : I just kept this one and my Martin vintage...
