Welcome firstly. In my honest opinion not that its the best one is that what you have said is true, you need to get the best grinder you can afford. I was in the same predicament sometime ago. I orginally had a sunbean, then crossed to a breville smart grinder which was good for what i could afford. After a while though looking through here i saw that for not much more you can get a compack K3 push or touch. Very worth while if you can stretch the budget a little, im happy with mine in many ways. Keeping in mind your budget though, Good luck.
