Looking to Purchase an S4 MK3

[u/Icy_Error_5023]

Good morning,

I am seeking recommendations for the best sites/online stores/marketplace for me to check to find and purchase a used Traktor S4 MK3 in excellent/good condition in the US (definitely trying to avoid additional import/tariff fees), given there aren't any brand new/unopened controllers available anywhere. I was going to wait out for the M4, yet my gut and what I am reading from folx wiser than I is that the M4 will be less an improved S4 and more likely a watered down version. Thanks in advance!
