[Lab] seeking feedback on steppers and spindle for my DIY CNC router

Double checking some things and found two problems
1 - it's not clear from the ad but it seems like the spindle is 55mm
(guessing on model and checking elsewhere) while the bracket is 52mm =
not going to work. A search for "55mm cnc bracket" finds some for $22.10
2 - that spindle seems to only have 3 wires=no hal sensor=no feedback.
Not sure but I think having hal sensors is a good thing so I need to
check for that.
3 - free shipping = won't have it this year, adding a few $ to get
faster shipping might be worth it.
If you want to have someone else to blame it does exist a complete kit
for $133.34+$40.53=173.87 at

(disclaimer, don't blame me if things doesn't work, do your own research
and tell me/this list about any issues found)
