Ron,

The accumulators are, in fact, not that expensive. There are online sources that sell tham for ~$110 USD each.

More often than not it is these which fail and you generally cannot tell from looking at them. Unlike the struts which tend to leak when they fail. Because of the relatively low cost I would re&re both accumulators first before replacing the struts.\

That having been said, the usual symptom of blown accumulators is a rock-hard ride and/or clunking as the car goes over a bump. Have you experienced either of these? Is it possible that the adjustable linkage which actuates the SLS valve could have detached from either the swaybar bracket ofr from the valve?
