propeller options

My plane recently had a 500 hr mandatory prop inspection @ over $6k, three out of 4 blades failed. Total coast to repair was quoted at around $17K. New props quoted at around $30K. I chose to install new props. The new propellers (hartzell) comes with operation limitation . " avoid continuous use between 2000 and 2350 rpm, Thats most of the crossing range!! do you know of any other option for propellers for the 1960 travelair with lycoming o-360 ? My mechanic is running out of ideas.

Model: Travel Air B95
Aircraft Serial Number: TD-445

I did some research and cannot find any other option than the Hartzell.

What do you think about the 2000 -2350 rpm operation restrictions? What are experiences of people flying the travelair with the upgraded new Hartzell Props?

Just saw the question, so sorry about the late reply, but maybe it'll make you fell better after spending the big bucks.. I've had the newer Hartzell props on a B95 for many years. I use full RPM for takeoff then reduce the props to 2500 for climb and use 2400 for all cruise operations. I leave the engines at full throttle during climb for the added cooling. I didn't measure it scientifically but believe I picked up a couple of knots with the conversion. I certainly have saved considerable dollars on maintenance over the props (92ZK's).
