First I would say try the LA before you buy to make sure it is something you want to use If it is, then go for it and get one you like.. Some require a lot of standing which may be a factor. Maybe your husband would like to use it too.
Don't let any guilt stand in your way. Like someone said, try as many as you can first to find the one that suits you
the most. If its something you really want, then do it! Have fun!
