I've been at this about 38 years now and haven't yet broken nor stripped threads on any drawbar or collet. Either I'm just lucky or the drawbars are of a better quality material and manufacture. Probably a bit of both. All the "turret mills" I've run were either a genuine Bridgeport or two different Alliant (Taiwan) machines with OE drawbars.
I bought a Dorian for the Alliant I have now because it didn't come with one, and later got a spare from a local Craigslist seller. I would build a power drawbar if I had no other priorities in shop equipment repair/upgrades. Right now I have to take apart my cheapo Chinese hardness tester to see why it won't calibrate, get my Black Diamond drill grinder "calibrated", make a new 50T gear for my lathe, and two more index plates for my dividing head.
Other things are getting in the way of all of that, so I'm going to do the right thing and take off on my bike in the morning and forget about everything.
