I agree with other posters that 10K is a bit steep, especially if you don't know if the tranny's history.
I bought our 2001 two years ago with just over 100K on the clock for $6700 (private party) with les than a 1000 miles on the third transmission. And then a few months later, a white 2001 came up for sale at I think $7500, with similar miles and with a rebuilt tranny as well as the 105K service completed (I was really tempted, white Odys are rare in my area and are much more visible to other drivers, unlike the gray one we have now which blends in with the sky and shadows and dozens of other gray ones at the mall parking lot).
It's your $, but I would shop around for a private-party one, it's worth more if it has a fresh tranny in it, otherwise, bugdet $3-4K for a tranny replacement on whatever you get and then hope you won't have to.
