I would say that cab is worth $500->$700 as long as everything in it works. EP1 + Computer would bring it back to the $2200/$2500 range.
Quoted from retired_user_101:

this might be something he could REALLY use in developing his prototypes.

I don't need another cab myself right now, but that's for the thought!
