Are the struts (electronic) unreliable on the 2008 dts?

The left front strut is bad on my 2008 dts. The dealer is the only place I can seam to find a replacement electronic strut and it is @$900.00. The non electronics struts are readily available. My delema is do I spend the big bucks to put an OEM electronic strut in only to have the other one or even the new on go bad in a year or two. Or do I just replace both front struts with non electronic ones and be done with it? Also if I do put non electronic on the front, do the rear still work? Any help would be great.
