My recommendation would be a v60, as fancy a grinder as you want, and watch a Hoffman video on technique/recipe. Once you've got the weights and motions nailed it's under 5 mins to make a brew from scratch.
good Informative post! but ditch the rhino and get a decent hand grinder from a brand like Kingrinder for the same price or cheaper (if going for a hand grinder).
Starter pack is usually a v60. A lot of places literally do a starter kit with some coffee, the v60 and some filters

You'll need is a grinder if you're not buying pre-ground, but that's totally an option too.

If you do get a grinder a hand one is cheapest, the Hario one is perfectly fine

But you can always spend more for a better one

Obviously an electric one is better. I'd say to avoid ones that have blades and are actually a spice grinder but tbh I used one for a while and it's passable if you're not a massive nerd.

A burr grinder is what you really want, there are some cheap-not-great ones and ones that go up to £thousands, but sticking with filter rather than espresso means you can get away with the cheaper end.

Also you should get some cheap scales. A decent one doesn't need to be more than £20

But I just use some "jewellery" scales

All that said, you could just use your Bialetti and either buy pre ground or grind your own
