To be honest Albert the PU bushes are relatively cheap it is the cost of the s/s crush tubes that are the expensive part. Due to the wall thickness for the strength they need to be drilled out and then turned from solid rod which is not cheap to buy and takes time. I've heard of PTFE rod (quite cheap and easy to turn) being used for bushes but in my belief i think this would certainly wear quite quickly. It is extremely low friction but easily damaged / work to.
As Phil says the PU removes all the road vibration from the suspension and makes for a very smooth ride. Some people say the PU wears and becomes sloppy after a while but i have had the same set in a car for 3 years and 12k miles and are still fine.
