I feel like I need a heavier built machine here are some i found. How important is spindle speed? Looking at these machines:

The syil x4 plus 200 - 3500
The Syil X4 Speed Master 8000-24000
The CNC Masters Jr. Mill 12 speed 120 – 3000

Any other machines should i be looking at? Ideas or comments you have would be greatly appreciated. Sorry i was not clear earlier.

thank you
