I would like to thank all who contributed to this forum, I will defiantly be renting some subs when needed and I have also been looking at used, but i’d rather get something with warranty incase my lack of experience puts me in place where I would loose my whole investment. I also have a question in terms of controllers and software, I have a mix track pro one with sera to into, I was thinking of selling it and buying a ddj sb because of the looks and extra performance features, however, I was thinking maybe i should upgrade to the full sera to instead and then in the future get the sb. Would that be a good call? thanks
