Was wondering on people's thoughts.

I have in my possession, a Hiro Trackmaster remote.  No idea where the engine went, so can't test it other then to say, it plays the sounds like any other remote.  Is it worth anything without the engine?

Worth quite a bit to someone with the appropriate engine but no remote, I would think.

You do sometimes see people selling remotes as spares. Like Dr. Chris said above, someone with the engine but no remote would definitely buy it.
