Monroe, KYB, and Gabriel quick struts are much better. They're good for at least 50k and have a lifetime warranty. Monroe's warranty even covers wear. Cheap Chinese struts rarely last beyond 10k.
If you can wait another 6 weeks or so, they run their annual fall rebate promos buy 3 get 1 free after rebate (September-October). This makes them more competitive in price to cheap Chinese struts.
If you can't wait that long, you should still get the name-brand struts. And if even those ar too expensive, at least get the Monroe Econo-Matics. They're not as good as Monroe's premium quick struts, but still better than Chinese (Econo-Matics might make it to 30k, but they have no warranty)
