I have looked, and I have searched the forums, but haven't found a solid answer. It looks like most people do both, but I don't really have the means to do both at the same time. One or the other sort of thing...at least for now(don't say save up, cuz that would take forever for a poor bastage like me)...anyhow... I want a stage one...everyone that I have read that has one loves it: better responce, better take off, more hp, all the good stuff. But nitrous is instant HP,(not really looking for anything more than a 75 shot, 50 would make me happy). What is the census on something like this? Is nitrous better to start with than a S1, or is S1 the building block for all?
