No phono input on Jadis but want to buy tunrtable

Have a Jadis OR integrated amp and I want to buy a nice turntable to get back into vinyl after more than 30 years....

I have no phono inputs. What do I need to buy to make sure that I have everything I need to make this operate properly?

And what should I is a good 'complete' turntable system for something in the $500-$600 range?

Thanks in advance. I really appreciate the terrific advice that I get from you all in here !
