I have a Ted Hendrickson wood prop on my T-18 my son has one on his RV-4, Ted made great props. My T-18 buddies like Aymar Demuth and other older props. My wife's RV-4 has a Sensenich composite adjustable 2 blade that Neal and I like a lot. There are many good props besides CATTO which I also endorse, having bought a 2 blade, and now a 3 blade.
If the price is right, go for it. Just make sure it's in good shape. If it needs to be serviced (fits loose on drive lugs, has a crack, chips in leading edge or other damage) pass it up. It may have potential, but not for a noob.
If you get an older wood prop, you should be willing to work on it. Don't worry, it's not hard. Get a good book or two, or Google wood airplane propellers. Soon you will be touching up worn varnish and re torquing prop bolts. Eventually you will be dismounting the prop to balance it, replace a damaged bit of wood or refinish it etc.
It depends on you.
I found 2100 RPM OK for flying into rain if the varnish has dried a few days. cruise speed is still over 130. But if you don't slow down and DO loose some varnish, it's often a small patch just inboard of the painted tip. Lightly sand it and re apply varnish. if the prop is a tad shaky, add a bit more varnish to the light blade
