I went french press because it is so forgiving. Put ground beans in container, pour over water and let it sit. You can of course go fancier, measure things here and there. But you'll get very far with very simple techniques, or no technique.
Speaking of grind fineness it's also very forgiving there as well. The finer the grind the shorter steep time is needed. I saw a video some time ago about this (there were a well spoken snob whose name I've forgotten, will find later) and the conclusion was that pretty much any grind will make good coffee.
Edit: I use one of these old timey grinders and I love it. Fair bit of grind variance being a perk. https://dygtyjqp7pi0m.cloudfront.net/i/25278/22826331_1.jpg
