I have no DJ experience. I am new to music creation. Traktor S4 looks like a lot of fun. I'd like to pick up the MK3 model but I cannot afford it. I have a chance to pick up a S4 MK1 for cheap. I saw a comparison video online that said the MK3 was a big improvement compared to the MK1. So I know I am not getting the best possible S4. That said, is there any reason I shouldn't pick up the MK1?
