I doubt there's much research about the mesh and vbac. The answer to that would just be a guess, no matter who is answering (doctor included). I did a presentation on VBAC in September to La Leche, and I do have some statistics I've gathered. The risk of uterine rupture for someone who has had 2 or more c-sections is 1.4%. The overall risk of a baby dying during a vbac is 0.046%. That is so much smaller than the rupture percentage because the rupture percentage includes scar thinning too - not just full breaks. The risk of repeat c-sections are problems with the placenta in later pregnancies(placenta previa and abruption), infertility, and the standard surgical risks. How VBAC is viewed is so biased because the rupture risk is over-emphasized and the risks of c-section under-emphasized. However, even if VBAC is safer in your case (which would be hard to know for sure), it would take a lot of conviction to stand up for yourself - finding a doctor to do VBAC mainly. (Some doctors seem to be supportive at first but then start pressuring for the c-section or an induction near the due date, even though induction makes a VBAC so much more risky.) It looks like it wouldn't be worth it to you since you are leaning towards c-section right now.
However, if you are interested in finding out more about vbac, beyond all the scare tactics, there is a conference in March on VBAC. If you register for the webcast, you can access the archives for free for a week after the conference. The website for the conference is: http://consensus.nih.gov/2010/vbac.htm.
