The OneSource brand prenatals are awesome.  I've been taking them for almost 2 years now (used them while trying to get pregnant and have been on them since) and couldn't be happier with them.  EXCEPT, I can't find them anymore.  Just the fact that these vitamins were $8 for a bottle of 275 and have 50% more calcium than a brand that costs almost 3 times as much for less is amazing.  They are nice small pills that have never made me sick.  EVER.  They also have many other vitamins that aren't even mentioned on other labels and have more 100% marks on there than even the One A Day and Nature...
