A respectable starter / mid performance machine, and fine for wood plastics etc.

He mentioned machining aluminium - ok for engraving but it would not be suitable for accurate machining:
Single ballscrew on X (racking)
Limited bed support causing workpiece deflections (due to single ballscrew design)
Very high gantry sides (tool deflection/vibration)
Gantry cross member on the small side (tool deflection/vibration)
Kress spindle (run out?, plus noisy)
Z axis plate too thin (10mm?)
