I actually think Merona at Target is pretty well made. You have to be selective as to what you buy, but I've had a pair of grey "dress" trousers for going on 4 years. Fit perfectly, hold up well, look professional and close $30.00 US.
I like Jacob and Mexx. I always try to pick up clothes during christmas sales. Club Monaco has really nice sweaters. I like Banana Republic for pants. Moon by Alfred Sung isn't bad either but better to buy when on sale.
