Saitek X36 is a USB 4 axis and seperate throttle stick. It has Digital Pots and should have little or no spiking issues in its lifetime. If one does go south on you I would highly reccomend sending it back to Saitek for replacement- they will piddle around forever in E-Mail for customer support but usually replace when it arrives on their doorstep with a note saying "diddlyed- please replace" and your address and phone #.
