Hi Bill,
   Your 8877 will be better (simpler & more economical to assemble, lower distortion, greater reliablity) than almost any transistorized thingy. 
  
   I've seen a few of the telco supplies at surplus outlets (the last one I saw was part of a cell-phone site) & on Evil-Bay but, I've not noted the details (make, model) as I've no personal interest in those.  The pricing of new units would likely be somewhat prohibitive.

73 & Good morning,
