To those with air ride systems, would buying the pieces separate off ebay come out cheaper than buying the complete system from airlift company or other places like that? Just looking at the bacic parts on ebay, it looks like most of the major parts are not that expensive. I need a list of all the parts of the air management system (not including the airstruts) so I can see if buying these pieces separately will save a couple hundred bucks. So far I've priced the components of : air compressor, air tank, (8)1/2 inch valves, and 100 ft of 1/2 inch lines.
