Best nursing tank tops?

Last time I had several of the the target brand ones and LOVED them.  Unfortunately I gave them to a friend about a month before finding out I was pregnant this time, and from what I've heard the quality/support has gone down significantly in the last few years.  

So I was hoping that a few of you could help me out with recommendations.  I would rather not spend $50 each on them since I would like to have 4-5 in my stash, but I may end up with a few just to get started.
