I’d highly suggest QIDI if you’re not building from scratch. I got my X pro back in 2018 and not only is it still stupidly detailed, but it’s an absolute workhorse. On top of that, they’re the best customer service I’ve ever had. I’ve made a ton of mods to mine over the years and they’ve done everything from helping me flash custom firmware to recording video guides for reversing the spin on the motors. I really cannot stress how great they are and how well they understand the DIY nature of this hobby.
