Lots of us don't have them. Before I'd even consider buying one I'd take classes. I hear alot of people who get them and then decide it's not for them. That's a lot of money to put out on something to decide you really don't like it or want to put the time into learning it really well. One store here offers classes and then you can rent their LA for a discount. This way after doing a few you'd know if it was for you or not.
I'm going to a LA advent at my LQS store this month. We will first hear all about it and they are going to show us things that aren't quilting that you can do with it and then we get to do hands on for the rest of the class. I'm really looking forward to that.
