POS for my new resturat

Hi guys, I’m Joe.
Im getting ready to oppen a resturant for my first time. The place I used to work used Digital Dineing and hated it. It had lots of problems with delivery and even with basic bookeeping stuff.
I just signed up here and read that one guy seems to really like Digital Dineing but most seem to like other things.

What is the best one? How much does a POS cost? What do I need to look for when I buy one?

My restaurant is going to be mostly carryout and deliver, but I hope we have a few tabels too.
