Where have all the good knees gone?

Where have all the good knees gone?

I'm looking for a knee to use in an inexpensive AK prosthesis. The old OWW knees and OB knees with constant friction and internal knee extension assists are apparently gone. Otto Bock still has their exo safety knee which may be modified to work, but I'm hoping there is another alternative.External elastic straps won't hold up due to kneeling. An endo knee with constant friction and knee extension aid that has a kneeling-tolerant knee cap might work.Generally these rare birds seem very expensive. Any suggestions would be welcome and posted. As a reference I consider $400 inexpensive.
   
  These patients are typically involved in construction-type work, have very limited funding, and require some degree of cosmesis along with durability.
   
  Thank you,
