You;re better off with Monroe, KYB, or Gabriel quick struts. Monroe and Gabriel will be running their rebate promo in a couple weeks (they do it every September/October). Buy 3, get 1 free after rebate. This makes the premium quality name-brnad quick struts competitive in price with the FCS and other cheap Chinese struts.
The cheap quick struts like FCS, Sensen, Unity, etc. rarely last 10k. The low-line blue Monroe Econo-Matci (blue) might not last 30k, and they have no warranty. Gabriel's new red Guardian Readymount is probably similar to the Monroe Econo-Matic.
Premium quick struts (Monroe Quick Strut, KYB Strut Plus, Gabriel Ultra Readymount) are good for at least 50k, and have a lifetine warranty.
Autozone often has a good price on Gabriel as well, and a no-hassle lifetime warranty that they honor with no problem at any AZ int eh country, and you don't even need to keep the receipt, just your phone number.
