Have had my blue Tokico non-adjuststables since '98 on several diff Sups... no problems with my Eibachs.
As far as being blown, everything I've seen about the blown ones suggest that ppl did not keep or replace the bumpstops (especially in the front). Anyways, for ~$200 a set and a couple of new bumpstops, I have no complaints at all... still feel great today.
Couple more years and they'll be 10 years old (10 years of use), still w/lifetime warranty.
