I can't even afford Motherhood unless it's on sale, they have gotten sooo expensive in the last few years. I did totally splurge on their new pants though and it was soo worth it!
Motherhood Maternity Clothes, Maternity Clothing and Maternity Accessories On-Line
They are so much more comfy than the elastic band pants, I remember by the end of both my other pg's, that I would be dying to rip my pants off by the end of the day because that heavy tight band across the top of the belly was soo uncomfy.
For other places, it's really hit or miss, sometimes you find something good, sometimes nothing, but when you do find something it's usually REALLY good as far as price/value. I'd say Sears, Ross, etc. Places like that. I got a couple of tunic shirts at Sears in the Juniors dept. that are long and wide enough for maternity, and I think they look cuter than a lot of maternity stuff does. I prefer things tops that conform to the belly, instead of the triangle shape tops that tent out around the bottom.
