Slings/carriers

Rachel • 24, Hull UK 🇬🇧 Expecting baby number 1, 👶👑 my little princess due 29th February
What are the best slings or carriers for a newborn? My LO is going through a phase of needing to be attached to me 24/7 
My friend advised a palm and pond ring sling but the reviews weren't very good. 
I don't have a lot of money to spend on one so either one that's cheap or is gonna last a really long time is preferable. 
I will add that I'm 6ft and med/slim build
