The bottom line
Haas ST-10: $39,000–$50,000 observed used. Biggest documented cost risk: Tailstock sticking is a documented, named failure mode on th. Buy only after inspection.
Haas SL-20: ~$16,900 to ~$41,000 used. Turning-center failure modes carry over from the ST lineage: spindle bearing, hydraulic-chuck/foot-pedal clamp faults, tailstock sticking, and turret/way-cover wear. Test clamping, tailstock travel and turret indexing.
