I have took your suggestions and ordered 12Nm Lichuan steppers LC86H3156 from Annie (there were no 10Nm ones).
4 motors with drives, brake, extra cabling and shipping 1200USD. VAT and customs fees not included.I don't know why shipping is so expensive. It costs more than 2 motors, 435USD. Makes me sad...

Also ordered UC300ETH-5LPT + UCBB breakout board + UCCNC. Found deal for 270EUR including VAT and shipping.

Thank you.
