Can recomment the Mares puck pro, it does everyting one really needs, incl. nitrox and altitude, and costs under 200 USD, sometimes 150USD only.
I also started with tables, got a computer when started diving again in 2018, and sometimes do deco diving up to nearly 60m with it. Works perfectly. One button, intuitive, easy to read, conservative which is fine, am getting older.
My buddies usually have computers for at least 3x the price, and hardly ever any significant difference in deco stops. I am not into gadgets so I am very happy with mine and see no need to change it and get anything more expensive.
