I've read several posts that deal with installing, but very few about removal. I've seen several cracked sprockets too. Surely I don't have to buy the special tool...what has everyone else done (that worked)?

It's tough, but simple. All you really have to do is find 3 bolts.
- Soak the sprocket in Liquid Wrench every 10 minutes - Get a regular harmonic balancer puller (3 slots for bolts) - Go find some SUPER hard-to-find bolts that will fit. - You'll need about 130mm long, grade 10.5 bolts if you can find em. (130mm x 6mm x 1.0 I think) - Add several washers, and lubricate all threads and hardware with moly or grease. - Torque each of the 3 bolts down evenly and make sure the puller is perfectly centered. - Block the puller from rotating AT ALL. I use a huge 4x8, 2x4's, and big clamps. - Soak it in Liquid Wrench again. - Impact wrench. I've done it by hand but the bolts shear easier.
I searched about 10 industrial supply vendors specifically dealing in bolts and hardware. These bolts are HARD to find. Finally found the bolts at a frickin PepBoys though, so there's hope.
As an alternative, you can buy Grade 5 threaded steel rod just about anywhere. It will shear off and explode about 20 times, but eventually you'll get it.

^^^ Bingo I found mine at pep boys too...lol They are the same thread size and pitch as the bolts for your timing belt cover and they need to be longer just like ^^^^ he said. I got mine off with no problems and didn't even break a bolt.
I edited to the wiki!
