Comanches are rare (but extremely cool). You'd be much better off finding a 98-01 Cherokee 2 door. If you DO find a decent Comanche, you can expect to pay quite a bit for it. They stopped making them in 1992 I believe... so many are rusted to death by now and the better HO 4.0 engines didn't come to be until 1996.
K, so scratch the Comanche as a beater... so how much for a 98-01 2 door cherokee 4x4 4.0? Hell I'd even take a clean 4door like you had.
Around here a decent condition 4x4 Cherokee is in the 3500 - 6500 range depending on condition. Since Jeep went away from the die hard 4.0 inline six and went with the terrible V6 engines, the older ones are actually bringing more money than they did two years ago... and nice ones are getting harder to find.
The Cherokee can be built into a seriously reliable 4x4 daily driver without breaking the bank.
