I need a new encoder. I currently have a Trans-Cal D120-P2-T. I can get
an overhauled exchange for $230. Should I do that or just replace it with
a new ACK A-30 or Ameri-King AK-350? The Ameri-King is the cheapest at
$150. I believe both the ACK and Ameri-King use an oven to compensate for
temperature variations, while the Trans-Cal does not. Is it better to
have one with an oven or without? Is the Trans-Cal a better encoder
making it worth the extra money?
