Just noticed this thread got bumped this month, oops.
I think Aquatics Unlimited is a pretty nice store. They have a very large variety of plants in stock and they get more in and sell out very quickly. I think some people would kill to have a LFS like this place in their town. Plus they have $0.99 and $1.99 clearance plants, you can't beat that.
Check out Hoffer's on 76th & Good Hope too if you get up that way, you should be fairly impressed.
I've never been to Vang's, but will be in that area tomorrow morning.
