Poor answer but I guess a bit of all round. I would have thought most have some sort of control over grain size?
I'm currently using a standard cafetiere and possibly want to move to drip - I do enjoy a slightly longer brew. I'm also intrigued by Espro's double press - in theory it allows you to grind a little finer and just seems more refined.
I guess I'd like to give aeropress a go too.
Thank you both - will look into the suggestions, may work out well in combination with buying an aeropress.
