~$10,500 (2001) to ~$32,900 (2019 TM-1P). A lower-duty-cycle toolroom mill; the common gotcha is the tool-release air system (a clogging Humphrey valve), plus family-level Haas spindle wear. Test tool release and listen at high RPM.

A documented Haas TM-1/Mini-Mill fault: a defective Humphrey valve clogs the tool-release air lines and tool release fails. Cheap part, but test tool release repeatedly before buying (Haas service video).
Cost not yet verifiedFamily-level Haas spindle: grinding or whining at high RPM is the most common Haas spindle failure, usually bearing-related. Lower duty cycle than a VF, but still check.
Cost not yet verifiedCoolant enters via front/rear bearing seals, the through-spindle rotary union, or the air-purge inlet when pressure drops, washing out the bearing grease. A 30-second ingress event during a coolant pressure spike can ruin a healthy bearing. Verify seal condition and air-purge pressure.
Cost not yet verifiedGrinding or whining sounds at high RPM — the most common Haas spindle failure, usually bearing related.
