Default build-your-own ignition coil for ej22?

My '96 Legacy has--at 166k--finally started to show signs of ignition coil failure. The usual, intermittent bucking symptom has been occurring, with the occasional low idle. (The sparks are spec and only 15-20k old).

As we all know, the replacements are over $100, compared to 1/4 or less of that for standard coils. I don't know the arrangement of this coil pack (and am kind of puzzled by the 3-wire-only harness), but wondered if a ubar-cheapskate like myself couldn't rig up something with a few standard coils--assuming of course I can find the space and aesthetic humility to do so.

Any ideas?

I have a friend who used the MSD ignition module for a Mustang V8. I think that's probably more expensive, though.

The ignition coil from a Dodge Neon is an excellent replacement. It sounds silly, but lots of us Legacy guys are using them. The stock coil puts out 28K volts, and the Neon coil puts out 34K.

An even better alternative would be an MSD 8239. This swap requires the newer type of spark plug wires on the 99' year, and the pigtail from a late 90's Dodge Neon.

Here's a link that deals with everything:
