the best shocks will cost 3 or more times what you paid for your blaster haha. a decent set are works. you could find some used works fronts for like 150-200 bucks and there not bad.
Fox floats for the front, Elka for the rear! Although I have definitely come to respect the Elka fronts. They are expensive, but they perform very well. If you are track riding and jumping big, I would go with elka's all the way around.
They are very expensive, but if you keep an eye on ebay you should be able to find a used set for much less than what a new set costs. Then you only need to pay to have them set up for your weight and riding style.
