I think it depends on where you are as to whether surgeons are not doing them as much. Here in the UK we have yet to have any horror stories and I'm pretty confident from the research I did that the band is as much of a viable option as the others.
My choice was based around not wanting to permanently alter my internal organs, the option for reversal, recovery time etc, but that was MY choice. The best you can do is lots of reading and think about what it is you want, speak to your surgeon and get them to discuss the options and statistics with you. If you look for bad you will find bad about anything. Good Luck!
