I have read the feedback on the coilover suspension system to replace the air shock system. Is this the recommended choice or will the standard fixed shocks I see advertized on ebay be as dependable? Any assistance is appreciated, as I am retired with fixed income and do not want to pay $400-£700 for one front rh air shock needing replacement. (Or does someone know of that one going for a reasonable fee?) Regards, Mike
