I’ve made up my mind i’m going modular 
Modular is amazing. Expensive, convoluted, time wasting, yet free and unique, a learning experience mostly its fulfilling once you've found modules you gel with and like the (i won't say sound) response of!
I've not heard and ACL modular, however i will reccomend Make Noise (especially their low pass gates LxD is a cheap small but fucking incredible sounding module, especially for percussion i emplore you to grab it), you'll want a Make Noise Maths because its lets you do so many things from envelope genration and groove creation to offsets ands crazy LFO's even can be some unqiue oscillators, very amazing module and is as great as folks say it is. Cwejman modules are also incredible, they are expensive and hard to find but they are worth the little extra expense and effort finding them or getting names on lists.
If you have any questions let me know Yorgoz! Also if your just starting out Doepfer cases are reasonable price, decent power supply (very important don't overlook this and don't get a Uzeus or any power supply that uses Ribbon cables over busboards for power distribution it adds crosstalk and noise your not going to like). Doepfer modules are really great prices too, so don't be fooled by more expensive utiility modules that Doepfer sell at half the price!!!
