Reply to Keep Kontrol S2 + Maschine or Buy CDJ-850/900 and mixer?

So I have been DJ'ing for maybe 3 years, started out with a M-audio Xponent, now have a Kontrol s2 and Maschine. These devices combined do everything I need and more which is awesome. I am now starting to be offered gig's at some popular local clubs and have been holding off accepting because i am too nervous/embarrassed to bring a controller setup, especially with no safety net if something buggers up. The promoter who was asking if i wanted to play said i could bring my setup no problem but i just don't feel right doing this. I have no experience on CDJ's either so I am not sure weather i could just walk in with a usb and spin on their setup as im used to Traktor. I can beatmatch manually without visuals etc but I am not comfortable playing a big gig like this without at least some experience on the gear.

So... I am now deciding whether I want to spend thousands of dollars on gear that does less than my controllers. Considering DJ'ing is a hobby for me and i would be playing a couple gigs a month for the experience/fun, which would not make me enough to pay for the gear its hard to justify. I don't mind spending the money I am basically just wanting some advice as to what CDJ's i should be considering. Ideally i believe i would like the 900's, but i know the 1000 mk3, 850, 900 are all around the same price. I was even believeing the 400's or 350's would be good enough for me to get used to the pioneer gear/setup. Only downside to that is if I ever host parties or do any mobile gig's id rather have the better gear. The last factor is the cool factor , the 850,900,1000 look a lot more professional than the 350/400's, although no one except me and other DJ's know the difference i suppose, and they couldn't look like any more of a toy then my controllers.

Anyone else been through this decision? I feel like if i went timecode/hid/midi it would be pointless as i have a full controller setup already. I mostly play funky/jazzy/minimal house and progressive/electro/trance. I don't do anything too fancy, just loops maybe some cue points and the odd effect here and there.

Any advice would be greatly appreciated!
