I've gone from stock to pro-line to UE racer-x and of the three the racer-x are far and away the best in performance, adjustability and durability. I'm not sure about the price but they work great and come with a great selection of springs for various weights and track types.
I would go either proline or ue. The ue are Back buggy shocks. You can run 4 in place of 8 of most other shocks. I have the ue and love them. I have bought 3 sets of 4 for 2 trucks.
Peace!
