Reply to Upgrade Ideas

Hey everybody,

Lately I have been wondering when the time comes if I should upgrade to CDJs or turntables. Currently I have an S2, F1 and akai lpd8. I have played a few gigs and I am currently about to start getting more and starting to try and put up posters and do events like parties, Stag and does, maybe weddings.Hopefully I will eventually play clubs but for now just events.

Right now I am in a partnership with a neighbour that has been DJing since the 70's and I am suppose to take over for him eventually. He hasn't really kept up with the different gear and primarily been using just a laptop for sometime, so gear is my department. I like my S2 and its worked fairly well but I'm worried about if it starts malfunctioning or if I play somewhere with different gear and won't be able to use my own I won't know how to use it. So I decided to ask my fellow DJTT'ers. What would be a good idea to upgrade to? I've seen a lot of people use CDJ. I like the idea that with CDJ's that you can use CD's a usb stick or a SD card to have music.
