What is your budget?
I was in your predicament not long ago, wanted the s8 but couldnt afford it. I ended up getting an s4mk2 and 2 x F1s, and I am having a blast with them all.
if you don’t mind looking at your computer screen then this set up can emulate almost perfectly the work of the S8, and for #200 pounds cheaper.
Good for stems and better for remix decks than the d2 or s8 I feel.
But even this is a pricey first buy especially if you haven’t mastered the basics.
I wish you luck I hope you get what you want. Shout me if I can help with anything.
