Maxxspeed or Tenzo r Coilovers

i kno i know you guys don't recomend coilovers because they suck at comfort and because of scary storys from your friend's friend's cars blowing a spring out the fender when the sleeve breaks. Anyways the local tuner shop here is offering me Maxspeed not Aerospeed (the one we all know suks for lots of problems ) for $150 there on sale right now he said there usually around $190. He said that there good and stacks up pretty good on other higher priced coilovers. He showed me the Tenzo R coilovers he said that they have steel sleeves and are way stonger than the alluminum ones, hes sellin them for $240 something like that. He told me he used to sell Aerospeed but since lots of his customers are gettin problems with them he stoped carrying them. Anyone here have experience with maxxspeed coilovers or tenzo R's are the sleeve on the tenzo R really steel and not alluminum? thanks for the help
