Blew $600 on a CNC conversion kit that was total junk

Picked up a kit from a seller on AliExpress for my old Bridgeport. Ad said it would work with Mach3 right out of the box. Nope. Steppers wouldn't even hold position after 3 tries. Never buying motor kits from China again without seeing real reviews first. Anyone else get burned on cheap conversion parts?

Found a used GeckoDrive setup on eBay for about the same money and it worked perfectly for years. Sometimes going with the cheap stuff just costs you twice.

Blew $400 on a "heavy duty" welder from Amazon last year that couldn't weld a soda can without blowing holes through it. It's the same pattern I see with tools and auto parts too. People always say "you get what you pay for" but on AliExpress or eBay you dont even know what you're paying for half the time. That GeckoDrive setup sounds like the smart play, especially if you can snag it used from someone who knew what they were doing.
