the S4 imo is actually a higher quality machine, what you need to think abotu sol is not "oooo i like the pretty colours.." but waht am i going to be doing in the future... if you want to stick to mobile DJing, i would say go the S4, it is more rugged, it is a better machine and it will help you in the long run because lets face it its made by traktor so it will flow in updated versions and will have more support from traktor if you plan to go into venue DJing then sol my man, the T1 is for you, if is EXACTLY like the pioneer CDJ set outs, the platters react the same as the 300/400, they have the same feel and size, and when you do go to a CDJ, the change will be seemless, where as if you had an S4, things will have to be re-learnt so you can flow as easily. so my man, the choice is yours happy choosing
