WTB: 1992 Eclipse RS 1.8L ECU

I need to see if I can obtain a computer (ECU) for a 1992 Eclipse 1.8L. I'm going to be buying this car off a friend from work that claims this is all it needs from the word of some roaming mechanic in town. He's going to see me the car for (I think) $600 to $800, but I want to see if I can purchase an ECU for cheap, that way the money I save goes toward insuring and registering the car! (I'm kinda in a hot spot right now with my OTHER eclipse not really running good and having problems for it passing smog! So this car would be a quick "drop and install" and go!)

To anyone who can help, email me at [email protected] or [email protected]. Thanks!
