I read the OP before voting, but no farther, so I voted $150k+ because we have $568k in mortgage (and at that, have about $125k in equity). But that's our *only* debt. We use credit cards for nearly everything, but pay it off every month; it's a convenience/bookkeeping thing for us.
Right now, paying off the mortgage is a fairly low priority. We have a good interest rate fixed for 30 years. Our minimum payment right now is just the interest; we've paid off a few hundred of the principal anyway, and left the payment the same, so we're making a few cents progress every month... but when the kids are both in school, our disposable income will go WAY up, and we can start paying $1000+ towards principal every month. We both have pretty stable earnings potential regardless of the job market, so it wasn't much in the way of a gamble for us.
True, we're paying a lot more in the long run than if we had a conventionally amortized loan, but we made that decision fully-informed. We wanted to buy a house we'd be happy to stay in for at least 20 years, so it made sense to put more into the loan so we could secure a place we wouldn't "outgrow".
And we looooove our house, and our neighborhood. ;-)
