Those you metioned, are worthless. Dynatek and Vortex are the only one's that work. Without major mods to your engine, you won't need a aftermarket CDI. Being on a budget, you can spend your money on other products. What mods do you have?

as of now I have a stage 2 cam k&n filter, ported head(nothing extreme) w/ +1 valves and 11:1 piston

The procom and big gun are the same one just different stickers. You will notice a nice difference. I can't run without one because the lack of rpms drives me nuts. They are a inexpensive mod, got them on my practice quads, and the vortex on the race.
