Yeah, I actually had a UBAC (unassisted birth after cesarean). I hosted this board for a few years, but got dropped for some reason. It's been really quiet here ever since.
I don't see why you couldn't have a vbac this time around, you just need to be very careful to find a supportive caregiver, one that's not going to put a bunch of restrictions on you or suddenly change their stripes near the end of the pregnancy and come up with lame reasons you can't have one (& most of the so called reasons they give are incredibly lame and totally contrary to the science).
I haven't kept up on a lot of the research since ds2 was born, but I'm sure I can find info if you need any. &
