If you're buying new ... the Koni Yellows are pretty decent from what I hear and reasonably priced. I probably wouldn't want to pay new prices for OEM suspension bits. If you don't mind a lightly used set, you can probably find the OEM stuff pretty cheap. I've seen OEM sets go for just a couple hundred with <10K miles on them.
