Your choice is easy.... Cheap. Good. Quality.
Pick
one.
If you don't care much about having to do a LOT of balance work, and you want "cheap".... TopFlite "Power Props" on Tower are about the cheapest out there. They really are crap props, though.
Slightly better, slightly more expensive, and "less" crappy are the Master Airscrew wood blades....
Good performance, and better quality ends up about $1.25 per inch.... average. Lots of choices there....
