Honestly, anymore, most doctors will recommend a second c-section due to the increased liability on their part. There is no harm in attempting a VBAC, but one does have to go into the process realizing that a section is a possiblity, because of the previous history.
Also, what type of incision was made in the first delivery? Lower transverse or straight down the middle? If you've got the former your chances of VBAC are better than with the latter. In fact, most docs won't even bother trying when the incision was down the middle (at least, none of the doctors I've ever worked with would do it, because of the way the muscles and the uterus were cut).
