Buying my first ukulele

Hey guys, I’ve been wanting to learn ukulele for a while and I’m finally thinking of buying one lol. I’ve never played any instrument before so I’ll be starting completely from zero.
ChatGPT told me a concert size would probably be better for me as a beginner, but I honestly have no idea. My budget is around 10–20k PKR.
Is this actually a good idea? And if yes, what ukulele would you recommend in this budget? Also, where’s a good place to buy one? I’m in Hyderabad but can get one from Karachi too, or order online if there are any reliable stores.
I mainly just want something that sounds nice and that I can learn songs on without needing to replace it after a few months.
Would really appreciate some advice from people who actually play.
