I am thinking about buying / playing war-hammer 40k, I've been looking at the space marine miniatures for a bit and have decided I will choose Space Marines, however I am unsure which chapter I should paint it, whether or not to choose one of the major ones like space wolves or grey knights or do something else. I would like to know your opinion, I will probably buy them in the very near future, what I would like to know is:
A ) What is the best starter pack, I've seen online that you should just buy a tactical space marine squad and a captain to start off practicing painting but if you think one of the starter packs are great then please recommend it (no more than 80-90$).
B ) What chapter do you recommend (and state why, e.g their specific miniatures look good, they have a interesting back story, cool looking chapter colors etc).
Also please mention a couple, like one main one you like and another that isn't commonly used.
