2.5 ignition

Have installed an '85 2.5 with tbi into my '85. When I got it it was missing the ignition module so I'll have to pay almost $200 to replace it (including the cost of the missing core). If I'll going to have to shell out the bucks for it does anyone know of an aftermarket upgrade for this aplication? On a lighter note I just scored a 5" lift from a rolled cherokee sport that was at pull'n'save. It didn't have any steering mods or longer track bar though. Makes you wonder how he went staight down the road.
