I have a Petersen which I don't use too often because it's fairly heavy compared to the cheap chrome ones. So, since I don't use it often I can never remember how to assemble the thing in a hurry (being mechanically challenged). Also, as Big Mick said, the knobs need to be tightened occasionally during use, especially if you have a pretty heavy songbook on the stand.

I also have one by Precision Instruments. It also requires unique assembly each time, but one advantage it has is that it can be set much lower than most stands. This is good if you are playing sitting down and want to not block your face or instrument from the audience. It's also fairly stable.

The cheap chrome one is quick and easy, but sways in the breeze and topples with my heavy Shaw Family Songbook on it. The best ones are those heavy duty black ones that all churches seem to have. I always use the resident heavy black stand if possible, because they hold position, can be set at any level and tilted any way you like, don't have to be assembled and don't have to be carried home!
