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

[Peter Sjoberg]

Have looked at spindle options and the way I see it I can get

a noisy 500w DC spindle for $80us at
https://www.aliexpress.com/item/0-5kw-Air-cooled-spindle-ER11-chuck-CNC-500W-Spindle-Motor-52mm-clamps-Power-Supply-speed/32723658779.html

a less noisy brushless 400W motor for (16.25+15.23)+93.44+10.55=$135.47us

Power:

Spindle:

Bracket:https://www.aliexpress.com/item/52mm-CNC-Spindle-Clamp-for-300w-400w-500w-600w-spindle-motor-52-mm-mounts-bracket-with/32693650409.html

So it's $55us extra for brushless and while it's not double $80 it is a
bit more, however I think it's worth the extra $$ and will probably
order it on Friday (all prices above are only valid on Friday).
