if you need to practice on different gear from your home gear in order to play out, you are not ready to play out by a long shot.
DJ Vintage you have 38 years of experience and I respect that, but when you (and I) started it was all TT and Vinyl. We didn’t have these dilemma’s when we started DJ’ing. So even tho I mostly agree with what you say we need to approach this from Michael’s perspective. I can understand coming to DJ’ing now feels like opening your first DAW, even tho the basics are all the same. I think the real problem is more psychological then it has really to do with gear.
Building up confidence is as important as building up your skills. Michael just wants to have that extra bit of confidence when he goes to his first gigs. In my opinion the way to become a ‘pro DJ’ is trough experience playing outside your bedroom. That experience gives confidence. The confidence that at one point builds towards him feeling confident towards every gear that he might come across playing outside.
Until that point comes why not choose a product that next to the fact that its a good quality product, gives you a little feeling of confidence when approaching your first gigs?
