Don't have the new prices, but the overhaul cycle is about 6-10 years on them (varies with engine and model). It's about $10K/side to do for both Dowty and Hartzell, if nothing's wrong. Replacing a blade is about $7K each. If a few blades need replacing it can get expensive pretty quick. The MT blades can be repaired if they're out of spec, and should in theory, not need replacing.
