adjustable or non-adjustable is really up to you. some people like to have the ability to adjust the ride (firm or soft). but if you get adjustable, its gonna cost you more.

here are some shocks off the top of my head.

koni yellow (adjustable, the best)
KYB AGX (adjustable, 2nd best in my opinion)
koni red
KYB GR2 (i think thats what its called)
tokico blues
tokico illuminas
bilstein (i'm not familiar with the specific models that bilstein has)

most people will reccomend the first 2.
