no g-code that sounds weird. The brother drill and tap machines even use g-code. I saw this dyna myte 2900 on LA craigslist today for 3k has a tool changer on it cool little machine also sold already. I to only have experience with haas but it sounds like you want the same machine as me. From my searching experence The kitamura mills have some awesome specs. The matsuura machines seem really solid with lots of info and parts available and usb upgradeable. I knew a guy who ran fadal he said it worked great but Imo his parts didn't look the best. There is also a benchman xt witch is a small cnc with ATC hard to find though. good luck!
